The title of director Jon Favreau's ("Iron Man") graphic-novel-inspired merging of sci-fi and Western leaves little doubt as to the groups that clash in it. A stranger (Daniel Craig) sporting a very strange wristband may be the salvation of a town ruled by a tyrant (Harrison Ford) and invaded by otherworldly visitors.
The cast also includes Olivia Wilde. Sam Rockwell and Keith Carradine ... but as might be expected, the true stars are the picture's special effects team. DVD extras: "making-of" documentary; audio commentary by Favreau; cast and crew interviews. *** (PG-13: AS, P, V) (Also on Blu-ray and Movies on Demand)
