Dave Franco is going back to school — but not to pursue a Ph.D in literature like his multi-tasking older brother, James. EW has confirmed that the younger Franco is joining the big-screen reboot of the 1980s TV series 21 Jump Street, playing a popular high school student who also happens to be a villainous drug dealer. Jonah Hill and Channing Tatum are set to co-star in the movie as narcotics officers who go undercover as teenagers in a high school. Rumors have circulated for a long time that Johnny Depp, who was vaulted to teen idoldom on the original 21 Jump Street, might make a cameo in the movie, which begins shooting later this month. Last year, Depp told EW he was open to the idea: “I’m hoping they’ll let me do a cameo,” he said, adding with a laugh, “Someone will say, ‘Whatever happened to Tom Hanson?’ and they’ll find me somewhere hoarding jars of peanut butter and shaking in my underpants.” But while a source close to the production says they would love the rumors to be true — and, according to Deadline, a day has been set aside in the production schedule for a potential Depp cameo — there’s still no official word on whether it will actually happen, with or without the peanut butter.
