September is bringing plenty of new films and TV series to Netflix, from returning favourites and gripping true-crime stories to glossy new dramas and seriously intriguing documentaries.

Here are the best new films and TV series coming to Netflix this September.Untold Raygun: Breaking Badly – 1 SeptemberRemember Raygun? Rachael Gunn’s unexpected appearance at the 2024 Paris Olympics quickly became one of the Games’ most talked-about moments when her performance went viral – and not necessarily for the reasons she’d hoped.

It promises a closer look at the woman behind one of the internet’s biggest sporting sensations.Turning Point: Generation 9/11 – 2 SeptemberTwenty-five years after 9/11, this new documentary looks at the generation whose lives have been shaped by its aftermath. Through the stories of children who lost parents, journalists who began their careers covering the War on Terror, young Afghans and Marines affected by America’s withdrawal from Afghanistan, it explores how the events of one day continued to reverberate around the world. Rather than simply revisiting history, it asks what the legacy of 9/11 looks like for the people still living with its consequences.The Gentlemen – 3 SeptemberIt’s been a year since Eddie and Susie joined forces to expand Bobby’s criminal empire overseas – but it seems things aren’t going quite to plan.

Expect friendship, ambition, plenty of dancing and the inevitable drama that comes when two best friends find themselves fighting to make it to the top.The Final Problem – 25 SeptemberThis new murder mystery has all the ingredients of a classic locked-room whodunnit. In spring 1959, thirteen people become stranded by a storm on a small island near Mallorca, only for English tourist Elisa Mander to be found dead in the hotel.
