June 20, 1941 –

Advertised as their farewell film (they went on to appear in two more,) The Big Store, starring the Marx Brothers and Margaret Dumont (in her final appearance in a Marx Bros. film) premiered on this date.
It has been rumored that British Prime Minister Winston Churchill was watching a private screening of this film when he received news that Nazi second-in-command Rudolf Hess had flown to Britain on an unauthorized mission to end the conflict between Britain and Germany during World War II. Churchill decided that the news was so unimportant he ignored it, went back into his screening room and watched the rest of the movie.
