Two Mules for Sister Sara (1970)

Two Mules for Sister Sarah (1970) stars Clint Eastwood as Hogan, a gunslinger who discovers a group of men attacking a young nun named Sara, played by Shirley MacLaine. He shoots the men dead and saves the girl, but begins to question if she's telling the whole truth about her profession after she displays some crude behavior that looks uncharacteristic for a nun. From cursing like a sailor, to smoking like a chimney, the hard drinking, hard talking Sara seems anything but holy. She also displays a bit more skin than the habit would allow, revealing some ample cleavage while riding a mule, again as she takes a dip in the tub, and early on, when she shows a side flash of her seat meat as she desperately tries to cover herself with a blanket. Then Clint's gun goes off and he tells her to get dressed in his typical stoic fashion.
