Jonah Hill has been cast as Jerry Garcia in Martin Scorsese's Grateful Dead biopic.
The 37-year-old actor will play the band's front man in the new movie, which will air on Apple's streaming service.
Scorsese and Hill have not worked together since The Wolf Of Wall Street.
The surviving members of The Grateful Dead, Bob Weir, Phil Lesh, Mickey Hart and Bill Kreutzmann, are set to be producers on the show.
Garcia's daughter Trixie Garcia, Eric Eisner and Bernie Cahill will also have input.
It is expected that the rockumentary will start off with the bands formation in 1960s California.
