If you are wondering what's new on Netflix September 2026, here are 10 movies and shows worth adding to your watchlist.

Note: Netflix catalogues and release availability can vary by country or region. Check your local Netflix app before planning your movie night.

1. The Gentlemen – Season 2

Release Date: September 3, 2026
Genre: Crime, Comedy, Drama
Best For: Viewers who enjoy stylish crime stories and dark humour

One of Netflix's major September releases is the return of The Gentlemen.

Season 2 brings Eddie Horniman, played by Theo James, back into the dangerous criminal world he inherited alongside his aristocratic estate.

This time Eddie is no longer simply trying to survive.

He wants to expand.

His growing ambitions put pressure on his alliance with Susie Glass, played by Kaya Scodelario, while new figures enter an already complicated criminal network.

The returning cast also includes Ray Winstone, Daniel Ings, Joely Richardson and Vinnie Jones, while new additions include Hugh Bonneville.

All eight episodes of Season 2 became available on September 3.

Why Watch It?

If you enjoyed the mixture of British aristocracy, organised crime, sharp dialogue and dark comedy in the first season, Season 2 is one of the most obvious September binge choices.

Netflix has also confirmed that the story will continue with a third season.

Show Room Verdict: ⭐ Top pick for crime and thriller fans.

2. Why Did I Get Married Again?

Release Date: September 9, 2026
Genre: Romantic Comedy, Drama
Best For: Couples, romance fans and viewers who enjoy relationship dramas

Tyler Perry returns to the world of Why Did I Get Married? with another chapter involving familiar couples, old relationship problems and new complications.

This time the characters reunite for the destination wedding of Marcus and Angela's daughter.

A beautiful wedding should mean romance and celebration.

Naturally, things become more complicated.

The film reunites Tyler Perry with returning cast members including Jill Scott, Tasha Smith, Michael Jai White, Richard T. Jones, Lamman Rucker and Sharon Leal, while Taraji P. Henson joins the story.

Why Watch It?

This is a good September option if you prefer relationship drama to crime and horror.

Marriage, friendship, family and romantic complications give the film a very different atmosphere from many of the darker releases arriving this month.

Show Room Verdict: ❤️ A good pick for romance and relationship-drama fans.

3. Call My Agent! The Movie

Release Date: September 10, 2026
Genre: Comedy, Drama
Best For: Fans of workplace comedy and European entertainment

Fans of the French series Call My Agent! have another reason to return to the chaotic entertainment industry.

Five years after the ASK Agency closed, Andréa is now trying to establish herself as a director.

Then disaster arrives.

Her leading actor disappears from the project just days before filming.

To rescue the production, Andréa reconnects with familiar members of the old ASK team.

The result brings the characters back into the world of actors, egos, entertainment-industry crises and behind-the-scenes chaos that made the original series popular.

Why Watch It?

If you want something lighter than September's crime and thriller releases, this movie provides a strong alternative.

It may be particularly enjoyable for existing fans, but viewers who enjoy show-business comedies may also find plenty to like.

Show Room Verdict: 🎬 A fun choice for fans of clever workplace comedy.

4. Crew Girl

Release Date: September 10, 2026
Genre: Young Adult, Drama, Romance
Best For: Teen drama and coming-of-age fans

Crew Girl follows Teagan Tao, played by Miku Martineau.

After a family scandal changes her life, Teagan moves to a small town and joins an elite prep school's all-boys rowing crew.

That immediately creates plenty of conflict.

There is competition.

There is rivalry.

There is pressure.

And there is attraction.

The combination of sport, school life and romance gives Crew Girl the ingredients of a classic young-adult drama.

Why Watch It?

Crew Girl could appeal to viewers who enjoy stories where romance develops alongside personal ambition and competition.

The rowing setting also gives it a different identity from the usual high-school romance.

Show Room Verdict: 💕 One to try if you enjoy YA romance mixed with sport and rivalry.

5. The Perfect Lie

Release Date: September 10, 2026
Genre: Mystery, Thriller, Drama
Best For: Mystery and psychological-suspense fans

If you prefer darker entertainment, The Perfect Lie deserves a place on your September watchlist.

The premise begins with four seemingly perfect couples.

Then one member of the group dies in a house fire.

The tragedy forces everyone else to question what they believed about their friends — and perhaps about their own relationships.

The central idea is simple but effective:

How well do you really know the people closest to you?

Why Watch It?

Secrets hidden behind apparently perfect relationships are ideal material for a mystery thriller.

Viewers who enjoy suspicious spouses, hidden motives, relationship secrets and gradually unfolding revelations may find this particularly appealing.

Show Room Verdict: 🔥 A strong choice for psychological mystery fans.

6. Physical 100: Italy

Release Date: September 11, 2026
Genre: Reality Competition
Best For: Fitness, competition and reality-TV fans

The Physical 100 concept heads to Italy.

One hundred Italian athletes compete through a series of demanding physical challenges, each hoping to outlast the competition and become the final champion.

The appeal of the format comes from more than simply strength.

Different challenges can favour endurance, teamwork, strategy and mental determination.

That means the person who looks strongest at the beginning is not necessarily guaranteed to dominate every event.

Why Watch It?

If you enjoy high-energy reality competitions, fitness challenges and unpredictable eliminations, this is one of September's most straightforward binge options.

It is also very different from the scripted dramas dominating much of the month's release schedule.

Show Room Verdict: 💪 Best pick for reality competition and fitness fans.

7. Monster: The Lizzie Borden Story

Release Date: September 17, 2026
Genre: True-Crime Drama, Psychological Drama
Best For: Adult viewers interested in dark historical crime stories

One of September's most talked-about upcoming Netflix releases is Monster: The Lizzie Borden Story.

The fourth instalment of Ryan Murphy and Ian Brennan's anthology focuses on Lizzie Borden and the notorious 1892 killings associated with her name.

Ella Beatty stars as Lizzie.

The cast also includes Rebecca Hall, Vicky Krieps, Charlie Hunnam, Billie Lourd, Jessica Barden and Sarah Paulson.

The series explores Lizzie's life within a repressive Victorian household and the violence that would turn her into one of America's most enduring true-crime figures.

Why Watch It?

This is likely to appeal to viewers who prefer psychological character studies and historical true crime rather than conventional detective stories.

It is also the first season of the Monster anthology centred on a female subject.

Because of its violent subject matter, it will clearly not be suitable for every viewer.

Show Room Verdict: 🪓 One of September's biggest choices for adult true-crime audiences.

8. Stranger Things: Tales From '85 – Season 2

Release Date: September 17, 2026
Genre: Animation, Supernatural, Adventure
Best For: Stranger Things and supernatural-adventure fans

The world of Stranger Things continues with another season of Stranger Things: Tales From '85.

Season 2 finds the gang facing another supernatural mystery.

With Valentine's Day approaching, ghostly apparitions begin appearing while strange creatures create new problems around town.

The animated format allows the Stranger Things universe to explore its familiar mix of friendship, monsters, mystery and 1980s nostalgia from a different perspective.

Why Watch It?

Existing Stranger Things fans are the obvious audience.

But the animated style may also make it interesting for viewers who enjoy supernatural animation and retro adventure stories.

Show Room Verdict: 👻 A must-check release for Stranger Things fans.

9. Best of the Best

Release Date: September 18, 2026
Genre: Comedy, Dance, Coming-of-Age
Best For: Feel-good entertainment and dance-film fans

Looking for something brighter after all that crime and mystery?

Try Best of the Best.

The story follows childhood best friends Maya and Anjali, played by Maitreyi Ramakrishnan and Priyanka Kedia.

They join UCLA's competitive Bollywood-fusion dance team.

What initially sounds like a fun college adventure quickly becomes far more competitive as the team pursues a US championship.

Friendship, ambition and intense competition collide.

Why Watch It?

Dance films work particularly well when the performances are connected to a strong friendship story.

Best of the Best also brings Bollywood-inspired energy into the college competition format.

It could be a good choice for a relaxed Friday-night watch.

Show Room Verdict: 💃 A colourful feel-good option for dance and coming-of-age fans.

10. A Different World

Release Date: September 24, 2026
Genre: Comedy, College, Coming-of-Age
Best For: Fans of nostalgic sitcoms and college comedies

One of September's most interesting television revivals is A Different World.

The new series follows Deborah Wayne, the youngest child of Dwayne Wayne and Whitley Gilbert, as she begins her first year at Hillman College.

But arriving at the university where her parents became legends creates a problem.

Everyone knows who they are.

Deborah wants to discover who she is.

She therefore sets out to create her own identity and legacy while experiencing college life with a new generation of Hillman students.

Returning connections to the original series give longtime fans some nostalgia, while the younger cast allows the new show to develop its own identity.

Why Watch It?

This could work for two audiences at once.

Longtime fans can revisit Hillman College, while younger viewers can experience the setting through a new generation of characters.

Show Room Verdict: 🎓 One of September's most interesting nostalgia-meets-new-generation releases.

More Netflix Releases Coming in September 2026

These 10 are not the only new releases arriving this month.

Netflix's September schedule also includes The AI Doc: Or How I Became an Apocaloptimist on September 15, The Doll on September 16, The Fixers on September 17 and Wonka's The Golden Ticket on September 23.

Later in the month, viewers can also look out for additional dramas, documentaries and international releases.

That variety makes September a particularly busy streaming month.

Which September Netflix Release Should You Watch First?

For viewers who want one recommendation above everything else, The Gentlemen Season 2 is a strong place to begin because it is already available and offers a mix of crime, comedy, drama and stylish British storytelling.

Thriller fans may want to move next to The Perfect Lie.

For something much darker, Monster: The Lizzie Borden Story is one of the month's most notable upcoming releases.

Viewers looking for something lighter can choose Best of the Best, while romance fans have Crew Girl and Why Did I Get Married Again?

There is no single correct answer.

The best September release depends on what kind of evening you want.

Best Netflix Picks for a Weekend Binge

If you have an entire weekend available, a returning series can be more satisfying than a single film.

The Gentlemen Season 2 has eight episodes available to stream, making it an obvious binge candidate.

Reality fans can dive into Physical 100: Italy, while supernatural fans can keep Stranger Things: Tales From '85 Season 2 on their list for September 17.

If you have only two hours available, one of September's movies may be a better option.

Best Picks for Thriller Fans

September is particularly strong if your favourite genres are crime, mystery and psychological drama.

Start with The Gentlemen for organised crime.

Move to The Perfect Lie for relationship secrets and mystery.

Then watch for Monster: The Lizzie Borden Story if you prefer historical true-crime drama.

This combination gives thriller viewers three very different styles rather than three versions of the same story.

Best Picks for Romance Fans

Romance viewers have options too.

Crew Girl mixes attraction with competition and young-adult drama.

Why Did I Get Married Again? approaches romance from the perspective of marriages, friendships and established relationships.

That makes the two releases suitable for very different audiences despite both containing romantic themes.

Best Picks for Something Light

Not every movie night needs murder, secrets or supernatural creatures.

Call My Agent! The Movie offers entertainment-industry comedy.

Best of the Best combines friendship, college life and competitive dance.

A Different World brings comedy and campus life together with a strong dose of nostalgia.

These may be better options when you simply want something entertaining after a long week.

Is September 2026 a Good Month for Netflix?

For variety, yes.

The September schedule covers crime, romance, mystery, comedy, reality competition, animation, dance, college stories, documentaries and true crime.

There is also a useful mixture of established franchises and entirely new stories.

Returning audiences have The Gentlemen, Monster, Stranger Things: Tales From '85 and A Different World.

Viewers looking for something new can experiment with Crew Girl, The Perfect Lie or Best of the Best.

That mixture gives September a broader appeal than a month dominated by one major franchise.

Final Thoughts

If you are searching for the best new Netflix movies and shows in September 2026, there is plenty to choose from.

Crime fans can start with The Gentlemen Season 2.

Romance viewers can try Crew Girl or Why Did I Get Married Again?

Mystery fans should consider The Perfect Lie.

True-crime audiences can mark September 17 for Monster: The Lizzie Borden Story.

Reality fans can test themselves from the sofa with Physical 100: Italy.

And anyone looking for lighter entertainment can add Best of the Best, Call My Agent! The Movie or A Different World to their list.

With releases continuing throughout the month, your September watchlist may become considerably longer before October arrives.

So grab the popcorn, choose your favourite genre and enjoy your next movie or series night.
