Two Mules for Sister Sara is directed by Don Siegel and adapted to screenplay by Albert Maltz from a story by Budd Boetticher. It stars Clint Eastwood, Shirley MacLaine, Manolo Fabregas and Alberto Morin. A Panavision/Technicolor production, the music is scored by Ennio Morricone and cinematography by Gabriel Figueroa.
Set during the reign of Emperor Maximilian in Mexico, plot finds Eastwood as a reconnaissance drifter for hire who saves a nun (MacLaine) from being gang-raped by three cowboys. Forming an unusual alliance as journey companions, it turns out that Sister Sara has many secrets to reveal...
It hardly set the American box office alight and critical reviews were lukewarm to say the least, and with Boetticher himself proving quite vociferous in his displeasure at how his source story was handled, Two Mules for Sister Sara is often thought of as a stinker. Is it? Well it's undeniably too long and Siegel is hardly stretching his directing prowess, but it's a fun adventure movie that is beautifully photographed and for the most part it finds Eastwood and MacLaine as a watchable double act. The central jokes of having Eastwood "fancy" a nun and said nun put into a number of compromising situations - wears thin because of the over long running time - but the film gets wrapped up nicely with some high octane action and a smile inducing ending.
Middle tier Eastwood and Siegel stuff for sure, and the prudes should stay away, but this is certainly better than its reputation suggests; flaws and all. 7/10
