Collin the Speedy Boy and Looney Tunes: When Worlds Unite/Transcript


  • Bugs: "Welcome to FingerTown! Population: Many Fingers?" Is this the place where creatures called Fingers lived?
  • Buster: Well, I heard stories that it was once Louisiana, but people had to evacuate 'cause of the dangerous Teary Eyeds.
  • Buster: Well, probably no cute girl lives here in- *sees Riley Logston and falls in love with her* FingerTown...
  • Diesel: Cooper, are you sure that we want that Tasmanian devil and that squirrel in our HQ?
  • Cooper: Pft! He appears very friendly.
  • Taz *barks (meaning: That's because I am!)*



  • With some exceptions, the majority of the cast reprise their roles from their respective shows.
  • There are differences added to the characters, including:
    • Elmer Fudd, Yosemite Sam and Marvin the Martian are allies to the main characters in the film rather than villains.
    • Yakko, Wakko and Dot Warner are the publishers and the editors of The Acme Acres Post newspaper.
  • The movie shares the same animation as The Chronicles of Collin the Speedy Boy.
  • This project started off as an anime crossover series, but as it was changed into a television movie, CTSB received a anime series, The New Adventures of Collin the Speedy Boy.
  • The Looney Tunes universe is modeled after The Looney Tunes Show universe, albeit with some differences:
    • The characters retain their The Looney Tunes Show Season 2 designs, but with their classic personalities, with Taz remaining as Bugs' pet.
      • As a direct result, the Tiny Toon Adventures and Animaniacs characters, as well as Squeaks, were redesigned to fit the series' design.
      • Also as a direct result, Bugs and Daffy's voices are closer to their classic incarnations' voices.
    • Daffy Duck's personality is more closer to his Robert McKimson's incarnation rather than the Chuck Jones' counterpart.
    • Mac and Tosh are siblings.
    • Sylvester Junior, Hector the Bulldog, Hubie and Bertie, who were absent from the show, appear in the film (Squeaks is an exception, since Wabbit came after the ending of the show).
    • The neighborhood is part of Acme Acres (the setting of Tiny Toon Adventures) rather than Los Angeles.
    • While Daffy Duck and Speedy Gonzales remain living in the same house, Bugs Bunny lives with Squeaks and Taz in his traditional rabbit hole.
    • Elmer Fudd remains as a hunter.
    • Gossamer is Witch Lezah's creation rather than her son.
