He owns his own island. He's one of the most bankable movie stars in the world. He can write his own ticket, career-wise. So Johnny Depp doesn't need to do a cameo in '21 Jump Street,' the upcoming film version of the dated and probably mortifying '80s TV cop drama that gave him his first big break.
That he's doing so anyway, according to Life & Style, shows what a mensch he is, what a stand-up guy. But then, it's just one of several instances throughout his career in which Depp has shown he doesn't put on movie-star airs but will stick by old friends, animal companions or even fans who are perfect strangers.
