The Best New Movies and Shows on Prime Video Right Now (August 2026)

Ride or Die debuted with a 96% critics' score on Rotten Tomatoes, hit number one on the Prime Video charts within 48 hours, and currently sits at number six in the UK. One reviewer wrote that Hannah Waddingham deserves to be the next James Bond. That's the kind of show this is.
Debbie and Judith have been best friends for years. Debbie thinks Judith is a forensic accountant. Judith is, in fact, an international assassin. When that secret explodes and a mysterious figure from Judith's past comes hunting, the two are forced on the run across Europe, with Debbie's corrupt politician husband tangled up in all of it.
What makes it work is the chemistry between Octavia Spencer and Hannah Waddingham. They're so good together you forget you're watching two Oscar and Emmy winners and just believe they're mates who've known each other for decades. The first two episodes are directed by Peyton Reed, the filmmaker behind the Ant-Man trilogy, and Ed Skrein and Bill Nighy round out a cast that has no weak link. Created by Tessa Coates. All eight episodes streaming now on Prime Video.

Five friends. A post-graduation trip to Thailand. A guided swim through a remote cave system called The Devil's Mouth. A freak storm the week before flooded the caves with sea life. Most of it died in the fresh water. Something didn't. And now it's hunting them.
Directed by Jeff Wadlow and starring Kathryn Newton, Lana Condor, Nico Hiraga, Gavin Casalegno, and Tommi Rose, this is a lean survival thriller that does exactly what it sets out to do. The script appeared on the 2019 Black List of Hollywood's best unproduced screenplays, and the entire film was shot in real freshwater caves in Thailand's Krabi province. The cast did their own climbing, diving, and underwater breath-hold work, giving it a physical authenticity that CGI can't replicate.
Critics are divided at 36% on Rotten Tomatoes, but audience reception on Prime Video tells a different story, with a 4.8 customer rating and a spot in the top ten action films on the platform. It's a Friday night popcorn film that knows exactly what it is. Under two hours, no filler, all tension.
