The Roommate

Given the Super Bowl and the icy weather, pundits didn't expect much from this weekend's box office, and 'The Roommate' mustered just enough mojo to meet those low expectations.

'The Roommate' may be a watered-down, PG-13 version of 'Single White Female,' but it was potent enough to debut at No. 1 with an estimated $15.6 million, about what experts predicted. Credit the TV fame of stars Leighton Meester and Minka Kelly, the youth-friendly rating, and a strong appeal to female moviegoers who weren't planning to watch football on Sunday. The suspense thriller's budget was reported to be just $16 million, only a hair above this weekend's estimated gross.
