Terminator Salvation slipped to fourth place, with about $16.1 million for the weekend, raising its total to $90.7 million.
Star Trek continued to have legs, coming in at fifth place, with $12.8 million for the weekend, raising its domestic total to $209.5 million, becoming the first 2009 release to cross the $200 million mark and outselling Monsters vs. Aliens to become the highest-grossing movie (domestically) so far this year.
