Let’s go ahead and declare this afternoon a high school comedy trailer double feature! Act One was Project X; Act Two is 21 Jump Street. The latter stars Jonah Hill, Channing Tatum, and Ellie Kemper, which we knew about, but there’s also Nick Offerman and Rob Riggle. And Ice Cube, and Dave Franco. And a party! Duh, because parties are an essential staple of the high school comedy. As are drugs and pooping oneself. And those aren’t even the best part of the trailer. (The best part of the trailer is when Ice Cube says “Twittersphere.â€)
