“21 Jump Street” is finally in theaters today, but one of our spies was lucky enough to attend the world premiere on Tuesday to give you a preview. There has been a lot of speculation about which stars, from the 80′s teen Fox drama the movie’s based on, would make cameos.

Johnny Depp, Peter DeLuise, and Holly Robinson Peete are all in it although Johnny and Peter skipped the premiere.  Riche Grieco, as we reported, is not in the remake, but did show up to the red carpet in a cruiser with sirens blaring!

Lastly, be sure you stay for the credits. That’s all I’m going to say.
