September 2026 is one of Netflix's biggest months of the year. Guy Ritchie's The Gentlemen returns for Season 2, Ryan Murphy's Monster anthology takes on the Lizzie Borden story, Russell Crowe leads the true-crime thriller Unabomber, and the long-awaited A Different World sequel arrives at Hillman College. Add licensed heavyweights like Straight Outta Compton, Smile 2, and T2 Trainspotting, plus a live boxing rematch for the ages, and there's more than enough to fill the calendar. Every release date below is verified against a named source.

Release dates are a working schedule — Netflix regularly shifts dates, times, and episode-release plans, and licensed titles can move with little notice.

What to Watch First

If you can't get to everything, prioritize these.

• The Gentlemen Season 2 — the most-anticipated Netflix return this month; start here if you only have time for one series.
• Monster: The Lizzie Borden Story — Ryan Murphy's anthologies are reliably big, and this case is tailor-made for the format.
• Unabomber — a Russell Crowe true-crime thriller with an R rating; catnip for the genre's audience.
• A Different World — a nostalgia play with a new generation, arriving mid-month.
• Straight Outta Compton — the licensed pickup most worth a rewatch before it inevitably rotates out again.
• LEGO ONE PIECE — a fun, family-friendly palate cleanser at month's end.
