Shrek - not cosmopolitans - was what fans were buying this weekend.

Despite competition from two heavily-promoted features, an aging green ogre was able to hang on to his title for two weeks in a row. Shrek Forever After raised an additional $57 million during the Memorial Day frame to bring its domestic total to $146.8 million.

Meanwhile, Warner Bros. proved that people can get tired of sex. Sex and the City 2 - which featured the return of Aidan Shaw (John Corbett) - couldn’t get past the bad reviews to even match the first film’s numbers. (Sex and the City opened to $56.8 million in May 2008.) The lovely ladies also couldn’t overpower Jake Gyllenhaal’s four-day haul. Prince of Persia: The Sands of Time wound up snagging second place with a $37.8 million debut.
