Sly Cooper was a planned 3D computer-animated film based on Sly Cooper and the Thievius Raccoonus. First announced in 2014, the film was to be produced by Brad Foxhoven and David Wohl of Blockade Entertainment; the original developer, Rainmaker Studios, left the project in late 2017. It was originally set for a 2016 release, though due to Rainmaker's departure, the actual release date is unknown, and the project has remained shelved since 2017.
Sly Cooper is a kinetic and comedic heist film that tells the story of Sly Cooper, an orphaned raccoon thief, and the adventures of his childhood friends and partners in crime, Bentley and Murray. In the film, Sly learns that he comes from a long line of talented, international thieves, and is catapulted into a global adventure. Sly races to reassemble pieces of an ancient book holding the Cooper clan's family secrets before it can fall into the hands of Clockwerk; an evil metallic owl bent on ending the Cooper family line. From romantic Parisian backdrops to the lush mountains of China, gritty film noir meets bright, colorful graphic novels in this origin story of the world's greatest thief-turned-hero.

According to Brad Foxhoven, after only a few months of development, Rainmaker and then-director Kevin Munroe had mostly "nailed" the look and feel of the film. Foxhoven also confirmed that Blockade and Rainmaker would be working closely with Sony and Sucker Punch Productions to make sure the film stays true to the franchise. Major changes, such as using CG animation rather than the cel-shading that has been a staple of the series, were supported by both Sony and Sucker Punch.
