12. Corey Feldman

Corey Feldman was arguably the least messed up of the “two Coreys” who often worked together, but considering that the other was Corey Haim that’s not saying very much. From his role in Stand By Me (which seemed to invent emo glasses twenty years ahead of time) and his weirdly uncomfortable performance in The Lost Boys, to his drug problems and odd behavior in later life, Feldman’s career has always delivered the requisite level of obnoxiousness.
