Oh, what a wacky band of brothers: Ice Cube is in negotiations to join Jonah Hill and Channing Tatum in a film remake of cops-in-high-school drama 21 Jump Street. If the deal goes through, Mr. Cube will play the role of precinct captain/father figure, which was originally played by Steven Williams. Cube is also shopping around a screenplay he wrote called Chrome and Paint, about custom-car culture in L.A. Paging Xzibit. [Deadline]
