Burt Kennedy who gave us so many good westerns spoofs comes up a wee bit short of good with Dirty Dingus Magee. Not that it doesn't have a few funny moments, but the cast just doesn't quite get with the spirit of the things the way they did in such films as The Rounders and Support Your Local Sheriff.
For one thing Frank Sinatra looks like he's waiting for Dino and Sammy to come on the scene. Old Blue Eyes in the meanwhile is just going through the motions of a performance. Which consists of him acting just like a human version of the Road Runner.
Wile E. Coyote in this case is George Kennedy who never played such a goofy role on screen before or since. Sinatra spends the entire 91 minutes of Dirty Dingus Magee consistently making a fool out of poor Kennedy.
Best performances in the film belong to the women, to Anne Jackson for one of the brassiest bordello madams ever done on screen and to Lois Nettleton as the nymphomaniac school teacher, Prudence Frost. Yes, the name is part of the gag.
But when that gag becomes the best one in the film, you've got a problem.
