Dr. Jekyll and Mr. Mouse/Trivia

This is the third Tom and Jerry short to be nominated.
Monster Jerry later reappears, decades later in the video game, Tom and Jerry in War of the Whiskers.
The episode's title is a pun on Robert Louis Stevenson's book Strange Case of Dr.Jekyll and Mr.Hyde.
A shot of the cartoon's original titles were found, but only in black and white. The original Technicolor version hasn't been found as of 2018. On October 7, 2018, a YouTube user cartoon98100 uploaded the full black and white titles of the cartoon taken from a 16mm Agfa print.
This episode is similar to Mickey Mouse's episode The Worm Turns where Mickey creates a potion to make small person be strong.
