Additional Information about the Theatrical Cartoon The Mysterious Package

This was the second-last theatrical Mighty Mouse cartoon. One of three shorts produced for inclusion in CBS-TV's Mighty Mouse Playhouse.



Mighty Mouse talks a lot in this episode.

Created by I. (Izzy) Klein in the spring of 1940, this character was originally designed as a fly. Paul Terry liked the concept, and green-lighted the project after changing the fly to a mouse called "Supermouse."

After two years on the screen, the Supermouse name was changed to Mighty Mouse. Some reports are that the threat of a lawsuit from DC Comics was behind this name change. Others insist that Terry did not want to compete against a character of the same name that an ex-TerryToons employee drew for Coo Coo Comics.

In any case, in 1944, the character's name was changed, and the Supermouse cartoons were retitled to the new name.
