“Masterminds” (**1/2 out of four) was a hit-and-miss but entertaining comedy based on the true story of the 1997 Loomis Fargo robbery about a none-too-bright redneck security guard (Zach Galifianakis) who orchestrates the robbery and is subsequently backstabbed by his cohorts (Owen Wilson and Kristen Wiig) and takes it on the run. No great shakes but ocassionally very funny, well-cast, and likeably dumb. Jason Sudeikis is a standout in an unusual role as a hard-core hitman.
