"Black Mass" is the latest true crime story to get the biopic treatment.

Johnny Depp plays the infamous Boston crime boss James "Whitey" Bulger, and in doing so, goes full Method for the part. Depp joins Hollywood's long list of actors who physically transformed themselves to mirror the real-life subject as much as possible. Some more so than others. (And we're loving Depp rocking contact lenses so blue that they make the Lycans from "Underworld" blush.)

In honor of "Black Mass" hitting theaters this weekend, here are 12 actors who look so much like their biopic counterparts it's kinda scary.
