Fast and funny account of Pancho Villa's invasion of the United States in order to get revenge on an unscrupulous arms dealer that double crossed him, only to get side-tracked by various mishaps and distractions.
Telly Savalas and Clint Walker are great as the smarmy Villa and his number one crony but Chuck Conners is wasted on the caricatured role of a gung-ho Colonel racing to repel Villa's army. All his scenes (particularly the fly in the mess hall) are cringe-worthy in their silliness!
All the fun is somewhat spoiled by the (historically accurate) sight of foreign invaders murdering US soldiers. These scenes would have been better off if they had been whitewashed as they undermine Savalas' "lovable rogue" performance, though it probably played better in those early-seventies days of "radical chic" than it does now.
Overall, the film is so fast-paced that you never slow down long enough to realize how dumb it is until the ending credits roll and Telly starts singing to you!
