How bad does a Marx Brothers movie have to be that even the Marx Brothers didn't want to admit to having made it? Most of the early books by — or authorized by — the brothers didn't acknowledge the existence of the last movie in which Groucho, Harpo and Chico appeared more-or-less together. In interviews, Groucho always referred to A Night in Casablanca (1946) as their last movie, ignoring the 1950 Love Happy. Okay, maybe Groucho had an excuse. His role was more of a glorified cameo, remembered mainly because he played opposite a then-unknown lady named Marilyn Monroe. But Harpo carried the bulk of the plot and even received credit for coming up with the story, which was originally intended as a Harpo-only movie. When he wrote his 1961 autobiography, Harpo Speaks!, he chose to forget about the film. Why? Well, you might get a clue if you watch the thing. Turner Classic Movies is airing it very early Saturday morning — 4 AM on the East Coast. At 4 AM, it might even be funny.
