Last week, the guys proved that two heads are really bad but three heads are ridiculously good. Well, how about FOUR heads?!? Or two sets of doubles? Thus, a double feature. One film is The Double starring Jesse Eisenberg playing two roles and the other is Enemy (based upon a book called The Double) with Jake Gyllenhaal as two characters. See how Hollywood's obsession with actors playing multiple roles holds up in these two films from 2013.
