Sidewalk Cinema

In the 1999 comedy Galaxy Quest, Sigourney Weaver, Alan Rickman, and Tim Allen star as has-been actors from a once-popular sci-fi show. When friendly aliens mistake them for actual space explorers, the “crew” is enlisted to help battle real alien bad guys. Herein lies the film’s darkest suggestion: What if reruns are the magnum opus of the human race? Still, despite the silliness, this is pretty tame, sweet fun. Allen delivers with well-studied Shatnerisms, and it’s great to see Weaver alien-busting once again. Outdoor movie screened at dusk. (PG-13) ORIANDA GUILFOYLE
