Ben Stiller's comedy 'Night at the Museum: Battle of the Smithsonian' debuted with $70 million at the holiday box office, beating the action blockbuster 'Terminator Salvation,' which made $53.8 million, studio estimates showed.

The figures put the 'Museum' sequel -- also starring Amy Adams, Owen Wilson, Hank Azaria, Robin Williams -- well ahead of 'Night at the Museum,' which debuted with $30.4 million during a three-day opening in December 2006.

'Terminator Salvation,' starring Christian Bale and Sam Worthington, actually debuted a day earlier than 'Museum,' bringing in $13.4 million on opening day on Thursday, for a grand total of $67.2 million.

'Star Trek' finished the holiday weekend with $29.4 million, while 'Angels & Demons' brought in $27.7 million.
