In honor of what would have been Groucho Marx's 123rd birthday, here are some pictures from Night in Casablanca (1946).
I haven't seen it in a while, but the Marx Brothers are quite funny.
When researching a bit, I found out that they were in a fake feud with Warner Brothers about the similarity of the film to the film classic, Casablanca. Leave it to Groucho to create a fake feud.
If you would like to see a sample letter from the "feud", it's at Chilling Effects. The originals are held at the Library of Congress.
