Even with powerhouse co-stars like Burt Lancaster and Laurence Olivier, this is Kirk Douglas' show, who served as star and producer. Just as he would remove Anthony Mann from Spartacus and bring in Kubrick, he fired Alexander Mackendrick a few weeks into production to bring in Guy Hamilton, a kind of cuckoo thing to do given that Alex had just delivered his crowning achievement, Sweet Smell of Success.
Based on the play by George Bernard Shaw, the story is set during the American Revolution and follows Lancaster as a man of conscience and Douglas as a man of action, and the events that lead them to switch roles to help the cause of the war. This was the third of seven films starring the two actors, and their real life friendship lends to an amiable chemistry in what otherwise is a fairly simplistic tale of conflict.
