Tom and Jerry (2021, alternate version)

Let's imagine if the 2021 film never focused on any human characters at all.

Changes

 * Tom and Jerry would be the main focus and only be the main focus.
 * Tim Story would still direct it, due to being a massive Tom and Jerry fan, but Brad Bird would co-direct it.
 * Tom and Jerry would start off as mortal rivals and gradually develop as vitriolic best friends.
 * The titular characters will have the personalities as they were in the classic shorts and in the Fast and the Furry, but given new traits.
 * Instead of a live-action/computer animated film, it would be a traditionally animated slapstick comedy adventure film in the style of the classic Tom and Jerry shorts of the Hanna-Barbera era and the Chuck Jones era.
 * Tom and Jerry would stay silent throughout most of the entire film like most Tom and Jerry media, but they would have to speak occasionally and/or consistently, like in some classic shorts, but their voice would never be overplayed like the 1992 film.
 * They would just be used at the appropriate time when the scene needed something particularly silly to up the humor.
 * Eddie Murphy would voice Tom and Jack Black would voice Jerry, but each would only speak sparingly for comedic effect.
 * William Hanna and Mel Blanc's vocal effects would be extremely used for Tom and Jerry, especially Tom.
 * James Newton Howard would compose the film, with the classic Tom and Jerry theme being added.
