In an episode of MAS*H(S2 E7 - LIP), they mistakenly state that "Flying Leathernecks" (the next film being shown on movie night) co-starred Ward Bond & Maureen O'Hara. This isn't true. They never appear in the picture. Robert Ryan was the most popular of the co-stars. Of course they may not as have known exactly who was in it based on the time of the release of the film, so it may have been an intentional error. Ward Bond and Maureen O'Hara did star in a number of movies along side John Wayne. The quiet man being one.
