Ice Cube and his wisecracking Barbershop gang have already defeated loan sharks and gentrification, so what are they going to do in the threequel? As the first trailer for Barbershop 3 proves, this time Cube’s Calvin Palmer is trying to stop gang violence with the help of old favorites Cedric the Entertainer and Eve, as well as new additions like Nicki Minaj and Lamorne Morris. Plus, Tyga pops up as a sketchy dude, which was probably not much of a stretch.
