Ben Stiller's Night at the Museum sequel out-performed Christian Bale’s Terminator sequel this weekend, hauling in $70 million at the box office. The comparatively low returns for Terminator Salvation ($53.8 million) had some wondering if Bale's tantrum on set (which became a YouTube sensation) hurt the film's chances. But executives said the movie out-performed others in the Terminator franchise, and called the results "excellent." The first Museum was a sleeper hit grossing $30.4 million its first weekend and then picking up $251 million by the end of its run. And good news for Hollywood: this year's box office revenue is pacing 8 percent ahead of last year's.
