Watch Magic Mummy (1933) Official Trailer

Tom and Jerry are police officers, driving around in their car and enjoying listening to some music on their police radio, when they hear a bulletin announcing another theft of a mummy from the local museum. They stumble upon the culprit, a mysterious and ghoulish man who is carrying a coffin through a secret door in a cemetery. They sneak in after him and watch him command the mummy to life; it is a beautiful woman, who he then commands to sing for his audience of skeletal theatre-goers.
