The movie character is darker and more sly than his somewhat goofy stage counterpart, but still retains a mischievous and carefree personality.
Mungojerrie is an impish and fun-loving cat, but with a more cunning and sinister side than his stage counterpart. Along with Rumpleteazer, he is one half of a notorious duo of cat burglars. Despite their roguish nature, the pair appear to be very loyal to each other.
Mungojerrie and Rumpleteazer are first seen singing and dancing along with the other Jellicles in "Jellicle Songs for Jellicle Cats"; they are specifically shown trying to break into a store during the "parasitical cats" line. The duo later come across Victoria, who has been left all alone after a Macavity attack. They let Victoria tag along as they break into a human house, introducing her to their reckless way of living while performing "Mungojerrie and Rumpleteazer". Together, all three cats run amok in the house, stealing food and valuables and destroying the interior of the house. As the song ends, they hear an angry dog barking and running towards them. Mungojerrie and Rumpleteazer quickly escape but upon realising Victoria has gotten her stolen pearls stuck to the bedpost, merely shrug and smile before leaving her behind.
Afterwards, the duo join the Jellicles in welcoming Old Deuteronomy to the Ball. They grin mischievously when they see Victoria again and appear unrepentant. They then dance along with the other cats in the "Jellicle Ball". When Bombalurina crashes the ball, Mungojerrie, Rumpleteazer and Griddlebone are revealed as Macavity's agents and help to catnip all the Jellicles. When Macavity kidnaps Old Deuteronomy and teleports away however, he leaves Mungojerrie and Rumpleteazer behind. Mungojerrie is violently confronted by Alonzo and the other cats but the pair claim they did not to know of Macavity's plan and just catnipped everyone for some fun. Mungojerrie and Rumpleteazer appear genuinely worried about Old Deuteronomy and join the other Jellicles in cheering on Mistoffelees as he attempts to rescue the Jellicle leader.
Mungojerrie is a calico cat. He wears a brown leather collar with a tag engraved with the letter "M".
