Hi guys, great episode, but you made an error regarding the history of anti-Nazi movies in Hollywood. The Great Dictator was not only not the only pre-WWII anti-Nazi film, it wasn't even the first.
The very first anti-Nazi Hollywood comedies were shorts by The Three Stooges, including You Natzy Spy! (1940), which preceded The Great Dictator by a few months. But there were other films, protested by the U.S. based German-American Bund (a pro-Nazi "lobby"), like Confessions of a Nazi Spy (1939).
