Sony has debuted a red band trailer for the feature adaptation of 21 Jump Street [21JST] on Facebook. Channing Tatum [CTATU] and Jonah Hill [JHILL] star as a pair of keystone cops who due to their youthful appearance are sent to work undercover at a high school. They get to relive the hazards of their teenage years while trying to bust a drug ring without being exposed as narcs. While the 1980s TV series had a serious dramatic tone, the movie update is played strictly for laughs like Starsky & Hutch meets Superbad.
