Let this trailer for Minka Kelly and Leighton Meester's The Roommate provide new college students with the potential warning signs to watch out for if you suspect your new roommate is a crazed stalker.

[ ] Do they watch you sleep?

[ ] Do they kill people and possibly a kitten?

[ ] Are you their only friend on their Frienderz page?

[ ] Are they off their medicine?

[ ] Do they disapprove of Cam Gigandet?

If you answered yes to any of the above questions (except for Cam Gigandet), your roommate is definitely not stable. You should move. And definitely don't agree to go see David Fincher's inevitable film about the creation of Frienderz together.

Check out the trailer after the jump...
