Followed by Tom and Jerry: Back to Oz in 2016.
Tom and Jerry & The Wizard of Oz contains examples of...
- Adaptation Dye-Job: Dorothy's hair is more brown than auburn.
- Adaptation-Induced Plot Hole: How do Dorothy, Tom and Jerry have the same dream? Of course, as per the sequel, everything wasn't All Just a Dream.
- Adapted Out: The psychic, alongside characters cut in the original film are never mentioned in this version.
- Amusing Injuries: It's Tom and Jerry, it's expected.
- Animated Adaptation: The film is an adaptation of The Wizard of Oz with some comedic elements added in.
- Anthropomorphic Shift: Toto's behavior and expressions are slightly more anthropomorphic than in the original film.
- The Cat Came Back: One scene pays homage to the Droopy cartoons by having Tom and Jerry trying to run away from Droopy, only for the dog to constanly show up right next to them.
- Compressed Adaptation: The scenes of Dorothy going to the psychic and meeting the Tin Man, Cowardly Lion and Scarecrow were completely cut. Although the latter are deliberately Played for Laughs because Tom and Jerry slept through that part.
- Crossover: A crossover between Tom and Jerry and The Wizard of Oz. Droopy and Butch/Spike appear as other MGM characters as per usual in these movies as well. However to the more astute history buffs so do the Oz characters. See the YMMV page for the explantion.
- Deliberately Monochrome: Double Subverted, television airings have farm scenes just slightly desaturated, while the DVD/Blu-ray releases include an alternate version of the film with the farm scenes retaining their 1930s colors (sepia, grayscale).
- Denser and Wackier: With the presence of Tom and Jerry, it is much more comedic than the 1939 film.
- Disneyesque: Characters from The Wizard of Oz are this, though Tom and Jerry keep their regular design.
- Furry Confusion: Tom and Jerry are Funny Animals who are treated like humans for the most part.
- Lighter and Softer: It's Tom and Jerry, it's expected. The added comedy adds more levity to the almost horror-like film.
- Mythology Gag: When Tom and Jerry grab on to the edge of the witch's castle, they quickly pose in a way identical to the iconic title card.
- Soundtrack Dissonance: Dorothy's opening song, "Somewhere Over the Rainbow", mostly focuses on Tom and Jerry fighting.
- Vague Age: Dorothy still looks and sounds like a teen. This leaves it vague whether she's 8-12 like in the original books or 16 like Judy Garland was. The sequel has Dorothy state that she will be 15 in eight months, putting her at 14.
- You Don't Look Like You: Toto is stylized less like a Cairn Terrier and more like a Scottish Terrier mix.
