The theme of homosexuality is obvious in even the most casual viewing of the film. Fredo's flamboyant clothing in Las Vegas. Fredo allows Moe to slap him. Could Don C. really be "doing the deed" with Mrs. C.? What a chore. I also have suspicions about Michael. Sonny seemed fine. So where could Fredo go in a world of more convincingly heterosexual men. Today it may not have been such an issue.
