Quite surprisingly, this was pretty good. Even Ricky Gervais was reasonably funny.
Premise is that because of a certain artifact, everything in the Museum of Natural History comes to life at night.
Cue Ben Stiller as the cliched divorced dad who needs some stability in his life (yes it's Liar Liar in a museum), cue three old duffers (Mickey Rooney, Dick Van Dyke and Bill Cobb) as the old guards. Cue various cameo related shenanigans.
It's bog standard family movie stuff, but it's pretty entertaining.
Night at the Museum - 7/10
