Sonic Across the Universe (or James Cameron's Sonic 4) is an upcoming American science fiction action film based on the Sonic the Hedgehog video game franchise and distributed by Warner Bros. Pictures. The film is a sequel to the 2018 Sonic movie, Sonic Returns and Sonic World Run and the thirteenth installment of James Cameron's Sonic Cinematic Universe. It is directed and produced by James Cameron and stars Chris Evans, Natalie Portman, Kristen Bell, Freddie Highmore, Dennis Quaid, Riz Ahmed, Will Smith, Drake Bell, Laura Harrier, Kevin McNally, Mahershala Ali, Jesse Eisenberg, and Robbie Coltrane.

Following the events of Sonic World Run, Sonic, followed by his uncle Chuck, travels across alternate realities of Time and Space to solve secrets about his past and reunite with his long lost cousin Sapphire and siblings Sonia and Manic. His adventure will soon lead him to an encounter with superhuman hedgehogs from other dimensions, with some joining his journey. But not all of them are as heroic as Sonic himself is as he will soon discover. Sonic must also be prepared when he once again comes across Scourge the Hedgehog, who will try everything to get his revenge over his previous defeat.
