It’s a full-on Speed reunion in the upcoming romantic thriller from Amazon MGM Studios, starring Keanu Reeves and Sandra Bullock. The project is still untitled.

Noah Oppenheim, who wrote the 2016 Jackie Kennedy Onasis biopic for director Pablo Larraín, Jackie, is penning the script. Plot details on the upcoming thriller are being kept locked up tight, but it is being described as “propulsive”.

Beyond a reunion for Reeves and Bullock after they co-starred in the 1990s action classic, as well as in the romantic drama The Lake House, the duo are reteaming with Mark Gordon, who produced Speed. Producing the picture are Sandra Bullock via Fortis Films, Reeves, Gordon and Bibby Dunn via The Mark Gordon Company, and Oppenheim and Sarah Bremner via Prologue Entertainment.

Reeves most recently voiced the video game character of Shadow in Sonic the Hedgehog 3, and will soon appear in the Ana de Armas-led John Wick spinoff film, Ballerina. Bullock last starred in the romantic adventure thriller The Lost City, opposite Channing Tatum.

Oppenheim recently served as a writer on the Netflix limited series Zero Day, starring Robert de Niro. Another of his screenplays, an untitled Kathryn Bigelow-directed White House thriller, is currently in post-production.
