Ice Cube plays Channing Tatum and Ice Cube's boss in Friday's 21 Jump Street, and we caught up with the rapper-slash-actor at their recent junket in NYC. Ice Cube talked about the good times he spent on the set with Channing and Jonah, though he jokes that both actors would receive Fs for their work as cops. Ice recounted telling Channing and Jonah "war stories" from his old days with NWA, and spoke about where he'd go undercover if he had the chance. Check out our interview to find out what Ice Cube's pick would be.
