What’s New on Netflix in September 2026: The Gentlemen, Unabomber, Monster: The Lizzie Borden Story and NFL Live from Melbourne

Netflix's September lineup leans into crime drama, returning favorites, and event programming. The month combines several high‑profile premieres spaced across September and a heavy single‑day library refresh on Sept. 1. If you want a quick watch plan: prioritize the dated premieres, slot a comedy or movie night around the Sept. 10 event day, and browse the Sept. 1 catalog additions for comfort viewing.

Guy Ritchie's The Gentlemen returns Sept. 3 with Season 2. The series continues the Horniman crime empire story with Theo James and Kaya Scodelario. The first season performed strongly worldwide and this installment promises more crime, dark humor, and power shifts.

Sept. 10 — Call My Agent! The Movie and NFL Melbourne Game

Sept. 17 — Monster: The Lizzie Borden Story

Ryan Murphy's Monster anthology returns Sept. 17 with the Lizzie Borden chapter. The series revisits the Fall River murders with stylized psychological drama and the franchise's trademark heightened approach to true crime.

Unabomber streams Sept. 25. The limited series stars Russell Crowe, Shailene Woodley, Annabelle Wallis, and Jacob Tremblay and focuses on the methodical descent into one of America's most notorious criminal minds.

Comedy and reality: New specials and series include a Stavros Halkias special, Crew Girl Season 1, and Kevin Langue content arriving with regular new episodes.

International and returning series: Fauda Season 5 and physical competition spinoffs (Physical 100: Italy) are part of the month, along with other returning reality and documentary franchises.

Catalog and movie drops (notable Sept. 1 additions)

Sept. 1 carries a broad movie and franchise drop that can anchor multiple nights of viewing. Selected titles listed for that day include: Sleepless in Seattle, Top Gun: Maverick, The DUFF, Phantom Thread, Scarface, the Alien collection, multiple Jaws films, Keanu, Knocked Up, and Liar Liar. This is the month's largest single-day library refresh.

• If you follow prestige crime and Ryan Murphy work, schedule Monster and Unabomber on their release dates.
• If you want event viewing with friends or family, put Sept. 10 on the calendar for the NFL game and Call My Agent! The Movie.
• Use Sept. 1 catalog drops for flexible movie nights or binge sessions of familiar titles.

September 2026 on Netflix is frontloaded with crime drama premieres and a clear event day midmonth. Combine release‑day viewing for the new limited series and returning dramas with the extensive Sept. 1 catalog additions for a mix of appointment TV and casual streaming.
