Hearts of the West (1975)

A drugstore cowboy heads West to pursue his dream in Hearts of the West (1975). Lewis Tater (Jeff Bridges) is an Iowa farm boy who writes dime-store cowboy novels and dreams of one day becoming a real cowpoke. So he heads out West, but before he can get there is mugged by two crooks. In the chaos after the attack Tater finds himself holding the thieves' loot box, and as he attempts to outwit (and outrun) them he stumbles onto the set of a Western, becoming an accidental movie star in the process. If you want to empty your six-shooter, you won't find a lot to work with here, because even though Susan Hendershot performs a bump-and-grind number in a cowboy hat and gun belt, her baby bullets are covered by pasties. That's a cool trick, Susan, but we'd rather see some wild wild breast.
