7. Robin Williams - One Hour Photo
Okay, stop me if you've heard this one before: Robin Williams walks into a comedy club and everyone leaves (cue crickets). No? Nothin'? Okay, maybe I'm not good at writing jokes but then again, neither is Robin Williams allegedly. Word on the comedy circuit for years has been that Williams is a notorious joke thief and comedians have been known to end their sets whenever he's seen in a crowd. So, in that respect it could be argued that he's not a nice guy, but with a cinematic resume that includes characters such as Popeye, Peter Pan, Mrs. Doubtfire, Patch Adams and that guy who made Will Hunting cry, Williams has put in some serious time playing good dudes. Then came the darkness that was One Hour Photo. Technically not Williams' most malevolent role - that came two films later when he played a stone cold killer in Insomnia - but One Hour Photo gets the nod because it was Williams' first foray into a role that was meant to be disturbing, rather than unintentionally disturbing like everything he did in The Birdcage. Williams went blonde which was freaky enough on its own to portray photo technician Seymour Parrish, a lonely little man obsessed with the lives of the Yorkins, a family that regularly uses his services. Sy makes copies of all their photos for himself so he can "live" with them and be part of the family through the pictures. Before long, Uncle Sy as he likes to think of himself takes it even further and enters the Yorkin's reality without invitation. Admittedly, "Uncle Sy" isn't truly evil. He's a disturbed and extremely dangerous man who just wants to be loved, to belong somewhere to someone. All pity goes out the window, however, when he pulls a B&E on the Yorkin's home and we're treated to the visual of him cheerfully dropping a deuce in their water closet in an effort to make himself to home. That's just wrong.
