Fox’s action comedy “Night at the Museum: Battle of the Smithsonian” fought to the top of a competitive heap during the long Memorial Day weekend, opening with a rousing $70 million in estimated domestic boxoffice.

Warner Bros.’ sci-fi actioner “Terminator Salvation” — the fourth “Terminator” pic and the first in six years — performed ably, if unspectacularly, with $53.8 million in second place on the four-day frame.
