Netflix, Apple TV+, and Hulu Headline Nine Major New Streaming Series for September 2025

September 2025 is set to be a landmark month for television as major streaming platforms prepare to release a diverse slate of high-profile series. From the return of established crime dramas to highly anticipated meta-comedies and legacy sequels, the upcoming lineup spans genres from psychological thrillers to romantic comedies. Leading the charge are Netflix, Apple TV+, and Hulu, offering a mix of original stories and fresh takes on classic properties that cater to both nostalgic fans and new audiences alike.

Crime and suspense dominate the early half of the month, beginning on September 3 with the second season of "The Gentlemen" on Netflix. Inspired by Guy Ritchie’s film, the new season follows Eddie (Theo James) as he expands his criminal empire into Italy, featuring a cast that includes Giancarlo Esposito. This is followed on September 9 by Apple TV+’s "Last Seen," a thriller starring Patrick Brammall as a police dispatcher whose life is upended by an emergency call related to his long-lost daughter. Spy fiction fans can also mark September 18 for the return of "Slow Horses," where Gary Oldman’s Jackson Lamb leads his team of exiled MI5 agents through a new series of deadly threats.

In addition to thrillers, the schedule includes significant entries in comedy and mystery. Paramount+ will air the final season of the romantic comedy "Colin From Accounts" starting September 10, focusing on the complicated reunion of its lead characters and their shared dog. On September 15, BritBox will premiere a contemporary adaptation of "Agatha Christie’s Tommy & Tuppence," modernizing the iconic detective duo. One of the most buzzed-about releases is Apple TV+’s "Brothers," debuting September 23. This meta-comedy features Matthew McConaughey and Woody Harrelson playing fictionalized versions of themselves, exploring the real-life rumors regarding their friendship and potential familial ties during a chaotic visit to Texas.

The month concludes with a strong focus on horror and cultural legacy on September 24. Hulu will launch the 13th season of "American Horror Story," which is expected to feature a supernatural narrative reuniting fan-favorite characters from previous seasons. Simultaneously, Netflix will premiere the sequel to the classic sitcom "A Different World." This new iteration focuses on the next generation at Hillman College, centering on the daughter of iconic original characters as she navigates contemporary issues within the HBCU community. These releases provide a comprehensive transition into the fall season, ensuring a robust selection of content across all major digital platforms.
