Trackdown

After vaguely promising a low-grade version of Coogan's Bluff ('straight' Montana cowboy goes to 'hip' LA in pursuit of runaway sister, who has drifted into prostitution), this settles into a run-of-the-mill vigilante movie. As the film-makers run out of ideas, they resort to mayhem as the solution to all their problems, and Jim Mitchum obliges by becoming increasingly bull-like. He tries hard to emulate the deadpan acting of his father Robert, for whom he could almost double, but - somewhat hilariously - gets it all wrong.
