The only screen credit on this film was "a Rudolf Ising Production." The short is notable for featuring the first appearances of the characters who would later be christened "Tom and Jerry" and would go on to appear in over 110 more short cartoons, seven of which won the Academy Award for Best Short Subject. As such, Puss Gets the Boot gave the animated duo their first Oscar nomination, though the short lost out to another Rudolf Ising MGM cartoon, The Milky Way. In the short, Tom's name is Jasper and Jerry is not given a name, but was known among the animators via model sheets as "Jinx". The plot set up the basic formula for Tom and Jerry cartoons for years to come, and as such, established many of the tropes commonly found in their shorts.
The short begins with the mouse later known as Jerry being tormented by the cat later known as Tom (we'll refer to them as such from here on, for convenience's sake). Jerry struggles to stay alive, being chased by Tom until he unwittingly knocks over a houseplant, raising the ire of Mammy Two-Shoes, his owner. She delivers Tom an ultimatum; if he knocks down one more thing, she'll throw him out. Jerry uses this ultimatum to his advantage, and manages to turn the tables on Tom by threatening to knock fragile things over for the rest of the short, and of course, Hilarity Ensues.
This short contains examples of the following tropes:
- Amusing Injuries: Notably less violent than the series would become later, though.
- Aside Glance: Jinx/Jerry winks at the 4th wall.
- Bowdlerise: UK airings keep Mammy's voice the same and only fix her spelling of "out".
- Cats Are Mean: Jasper/Tom is much more mean-spirited in his debut than most of his later appearances, bordering on sociopathic.
- Dish Dash: Jinx/Jerry piles dozens of dishes into Jasper's/Tom's paws near the end of the episode, and then causes him to drop them, getting Tom kicked out.
- Early Installment Weirdness: While Jerry looks slightly different from his more famous incarnation, Tom is completely unrecognizable, looking and sounding more like a real cat. It's rumored that his heavy retool came mostly from the directors realizing that the more realistic he looked, the less funny it would be when he got hurt.
- Exactly What It Says on the Tin: The puss got the boot.
- Eye Scream: Jerry poking Tom's eye near the beginning of the short.
- The Faceless: Mammy Two-Shoes
- The '40s
- Iris Out
- Just Toying with Them: Jasper is content to simply play around with Jinx, and while tormenting him, has no intentions to harm him. That is, until Jinx punches him right in the eye. Jasper becomes determined to eat Jinx for the rest of the cartoon.
- Karmic Trickster: Jerry/Jinx
- Kick the Dog: It's pretty clear from the beginning who the antagonist is supposed to be as we see Tom toying with Jerry.
- Literal Ass-Kicking
- Misspelling Out Loud: Mammy misspells "out" twice in this short (first as "o-w-t," then as "o-u-w-t"). More recent version use the less racist re-dub which does away with this unflattering character trait, although it did pop up in a different cartoon from the same creators a few times.
- No Name Given: For Jerry/Jinx, and Mammy Two-Shoes.
- Now I Lay Me Down to Sleep: Jinx says it when he's caught by Jasper, though it's sped up in a chipmunk-like voice and hard to distinguish.
- One-Shot Character: Jasper and Jinx originally were destined to be this, but positive reaction to this short caused the executives to decide that more should be made, and the Tom and Jerry series was born.
- Pun-Based Title: An obvious play on "Puss in Boots".
- Sassy Black Woman: Mammy of course.
- Say Your Prayers: Jerry/Jinx does this in a high-pitched chipmunk voice when Jasper/Tom catches him by the tail.
- The Speechless: Mammy is the only one with spoken dialog, besides the aforementioned Say Your Prayers scene, which is unintelligible anyway.
- Spoiler Title: Yes, at the end the 'puss' does indeed 'get the boot'.
- The '30s: As it was released in early 1940, it gives a glimpse into the cultural 30's/Depression Era. Downplaed a bit, however, because except for in America, the 30's ended in 1939 with the start of WWII.
