Minka Kelly, Leighton Meester in The Roommate. Pray for Late Night Pillow Fights.

It’s basically a 20-something version of 1992’s “Single White Female”, though most of the kids who will be seeing this thing probably have never even heard of “Single White Female”, or seen its lackluster direct-to-DVD sequel, “Single White Female 2: The Psycho” (the title of which, if you’ve seen the franchise, is sorta redundant, but I digress). The 2009 version will be set in college, and is being described as a psychological thriller that will star Leighton Meester (of Gossip Girl fame) as an insane college co-ed who becomes obsessed with her roommate, played by Minka Kelly (of Friday Night Lights fame). Christian E. Christiansen will direct for Screen Gems.

THR says the film will also star Aly Michalka, Matt Lanter, and Cam Gigandet. Michalka will play an outgoing dormmate determined to give Sara (Kelly’s character) a social life, while Lanter (of the new 90210 fame) will play Sara’s ex-boyfriend. Gigandet (“The Unborn”) will play her current boyfriend.

For those who have seen the original “Single White Female”, don’t get your hopes up that Kelly and Meester, both very fine looking nubile young lasses (below), will be doing more than screen teasing ala the recent “Obsessed” with Ali Larter and Beyonce. My guess is that “The Roommate” will be aiming for a PG-13 rating, considering that the cast is made up entirely of popular actors from popular teen-centric TV shows. The demo is there for the taking, and a risque R-rating is not gonna happen as a result.
