Dave Franco is joining the big-screen reboot of the 1980's TV series, 21 Jump Street, whereJohnny Depp got his big break. Rumors have been going around for a long time that Johnny Depp might make a cameo in the movie, which begins shooting later this month. Last year, Johnny Depp said, "I'm hoping they'll let me do a cameo," and SO ARE WE! But, alas, it's still just a hope because nothing has been confirmed yet. Keeping fingers crossed!
