Don Siegel's "Two Mules For Sister Sara" starring Clint Eastwood and Shirley MacLaine is certainly not one of the brilliant Westerns with Eastwood, but it is a very well directed, greatly acted and very amusing little Western comedy with good wit that highly entertains. Eastwood, who is cool as always, and the lovable MacLaine match perfectly, and the plot has some nice twists (although it should be said that some of the 'twists' are not really too surprising).
After gunsling Hogan (Eastwood) saves a nun named Sara (MacLaine) from a bunch of guys who wanted to rape her in the middle of the desert by shooting them, he now has to take care of her, which annoys him. It's a time of revolution against the French in Mexico, and while Hogan, who is interested in quick money, will fight for whichever side pays well (which happens to be the revolutionaries), his new traveling companion Sara is very obviously an idealistic supporter of the revolutionary Juaristas...
As mentioned above, "Two Mules For Sister Sara" can in no way come up to the brilliance of Eastwood movies such as Leone's Dollar Trilogy (few movies can) or Eastwood's very own "High Plains Drifter" of 1973. Nevertheless, it is a good little western with a lot of charm and wit, which provides an exciting story, action and great entertainment as well as many good laughs. Clint Eastwood has always been the epitome of coolness, especially in his Westerns, and MacLaine is great in her role of the feisty sister Sara. Overall, "Two Mules For Sister Sara" is a highly entertaining Western Comedy, that will not leave anybody bored. Recommended! 7/10
