Mercury Wonder Show
Mercury Wonder Show was a show started by Orson Welles in 1943 that traveled to Armed Forces camps and performed magic tricks and comedy. The show was broadcast live over radio from the camps.
Welles performed his Mercury Wonder Show magic act as a cameo in "Follow the Boys". It's the piece of the show on film and you see Marlene Dietrich sawed in half after Columbia Pictures refused to allow the original show performer Rita Hayworth to participate.
Elements of the show were included in Welles production of "Around the World" which played at the Adelphi Theater in New York.
