The Day Copper-9 Stands Still/Tropes/Trivia

• Acting for 2:
  • Bob Bergen voices Porky, Jeff, & David.
  • Eric Bauza voices Daffy & Marvin (the WDF member, not the martian).
  • Elsie Lovelock, Michael Kovach, Sean Chiplock, Caitlin Dizon, & David J. Dixon return to play multiple characters they voice in the series, with Kovach also playing a moviegoer who watches the film itself, & Dixon playing a new character named Jim.
  • Janice Kawaye voices Jennifer & Petunia's test robot who appears in a flashback.
  • Ruth Clampett returns as Waitress Maude while also playing a member of the WDF named Anna.
• Billing Displacement: The cast is arranged by alphabetical order, & even the characters they play get this treatment as well. This leads to prominent cast members such as Elsie Lovelock, Michael Kovach, & Candi Milo receiving lower billing on the list, minor cast members such as Ruth Clampett getting high placement, & major characters such as Uzi, N, & Porky to be billed last among the characters played by their voice actors while minor characters such as Braidon are billed 1st.
• In Memoriam: The film is dedicated to former animator Bob McKnight, who died before the release & after the production of The Day the Earth Blew Up.
• Meaningful Release Date/Milestone Celebration: The film was released on April 19, 2030, coinciding with the 100th anniversary of the Looney Tunes franchise. The pilot of The Gaslight District was also tied to screenings of the film to celebrate the show's 5th anniversary.
• Role Reprise: Literally everyone in the cast have already voiced certain characters they play before.
• The Original Darrin: Bob Bergen takes over again as Porky Pig from fellow voice actor Eric Bauza, who voiced him in The Day the Earth Blew Up: A Looney Tunes Movie.
• What Could Have Been:
  • JT Music's original song for the movie, "Persistent" (specifically its nightcore remix), was going to be used in the final battle. It was instead replaced by a mashup of "BITE ME"'s nightcore remix & "Let's Get Looney".
  • Permanently killing off Uzi & V at the end of the movie was a huge debate already in the writing process before they ultimately decided to go through with it to make things more different from the original show.
  • When adapting "Home", Porky & Daffy were originally going to help out, but it was cut since the writers figured Uzi wouldn't want anyone disturbing her hacking process.
  • Uzi going through N & V's memories was also going to be trimmed down, but it was ultimately decide to leave it back in to help explain the situation better.
• Word of God: According to executive producer Pete Browngardt, this movie is not canon to The Day the Earth Blew Up.
  Pete Browngardt: 1 thing about working with the Looney Tunes is that you don't necessarily have to establish continuity in & with future installments, even if they might feature the same cast of characters.
