New Trailer: Hill & Tatum Star in '21 Jump Street'

In theaters March 16, Jonah and Channing play Schmidt and Jenko, two former high school nemeses who become unlikely friends at the police academy. Untested and the joke of the force, the pair get a chance to shine when they're assigned to go undercover as students to bust a drug ring. But can they blend in with today's more complicated youth cliques – and will their awkward teen neuroses get the best of them?
