Russell Brand has christened it "the only film better for leaving Johnny Depp out".
Although the original TV series of 21 Jump Street propelled Depp into the stratosphere, the film is relying on a group of more solid, already established talents - Jonah Hill and Channing Tatum and Ice Cube.
Stars rocked up for the premiere in Los Angeles - see our video below - and here's some blurb about the film, which hits UK cinemas on Friday 16 March.
In the action-comedy 21 Jump Street, Schmidt (Jonah Hill) and Jenko (Channing Tatum) are more than ready to leave their adolescent problems behind. Joining the police force and the secret Jump Street unit, they use their youthful appearances to go undercover in a local high school. As they trade in their guns and badges for backpacks, Schmidt and Jenko risk their lives to investigate a violent and dangerous drug ring. But they find that high school is nothing like they left it just a few years earlier - and neither expects that they will have to confront the terror and anxiety of being a teenager again and all the issues they thought they had left behind.
