It's one thing to walk into a 'Halloween' or 'Friday the 13th' movie and know what's coming your way. The guys in the masks carrying big blades are clearly the ones you should be running from. But what happens when someone doesn't have "killer written all over their forehead?" See, those are the ones that you have to watch out for, the ones with the ability to pose as nice, normal people, but then do a complete 180 once they've worked their way into your home and life.

The premise of the upcoming film 'The Roommate' is really quite clever. A college campus is an opportune location for a silent threat to take advantage of a new student's vulnerability. In honor of Rebecca (Leighton Meester) preying on her random roommate, Sara (Minka Kelly), in theaters this weekend, we're taking a look at some of the other deadly characters who used the sneak attack approach to get the one up on their victims.

They're lethal, murderous and at time psychopathic, but when you first meet these folks, they're as harmless and friendly as they come.
