Where can A Night at the Museum (20th Century Fox, 12.22) go past the inanimate-objects-coming-alive premise unveiled in the trailer? That’s the question you’re left with after watching it. Pic stars Ben Stiller as a hapless Museum of Natural History night watchman (is there any other kind in a film like this?) who “accidentally lets loose an ancient curse” that blah, blah. It sounds fun, looks like fun…but in a lightweight Jumanji way. Amd keep in mind that the dreaded Shawn Levy (The Pink Panther, Cheaper by the Dozen, Just Married) is directing.
