Man of La Mancha (1972)

This is abysmally bad. 

 See, the only good thing about Man of La Mancha, which is, frankly, a terrible and terribly confusing musical, is the song "The Impossible Dream". (It has a one or two other ok songs.) 

But when you cast Peter O'Toole and Sophia Loren – both big stars without good singing voices – you might find yourself with a well-acted film, but well acted in service of what? 

Man of La Mancha is just kinda stupid, so you have these excellent actors speaking insipid dialogue. And then you cast James Coco as Sancho Panza??? Coco is a broadly funny clown. He would work onstage in the role but not with these two leads. This movie is just awful.
