Trivia: Liv and Maddie

  • Acting for Two: Dove Cameron plays both Liv and Maddie Rooney. See also Stunt Casting below.
  • The Danza: Joey Bragg, who portrays Joey Rooney.
    • One of Dove Olivia Cameron's two roles is Olivia "Liv" Rooney.
  • Hey, It's That Guy!: Bridget Shergalis, who plays Maddie's friend Stains, does a lot of character work for various Disney Channel and Nickelodeon shows including Dog with a Blog and See Dad Run.
    • Ocean, Liv and Maddie's friend, is also Jordan from Mighty Med.
    • Artie is Albert.
    • Ally Dawson was abandoned as a little girl on a camping trip and consequently raised by wolves (and consequently helped Liv get into character).
      • Kel as the break-dancing instructor from the same episode.
    • Neal Schweiber as Joey's boss at the mall food court.
    • Raquel Castro as South Salamanca.
      • Marla Maples, best known as Donald Trump's second wife, as Amy Becker in the same episode.
    • Halfrek went from being a vengeance demon to being a happily married mother of four.
    • Principal Jindrake is a little less evil in Stevens Point, Wisconsin.
  • Retroactive Recognition: Dove Cameron previously had some prominent guest roles on Shameless
  • Romance on the Set: Dove Cameron is dating Ryan McCartan, who portrays her (Maddie's) love interest, Diggie.
  • Stunt Casting: In "Grandma-A-Rooney," Patty Duke plays Grandma Janice and Great-Aunt Hillary. She has some experience in playing twins. Also counts as Actor Allusion.
  • Unintentional Period Piece: The first season of the show is clearly filmed in early 2013, with everyone using iPhones with iOS 6 (in one scene the default iOS 6 wallpaper is shown) or Samsung Galaxy phones and tablets.
  • What Could Have Been: It was originally planned to have just the twins, a separate project based around Joey Bragg was folded in.
    • The plot is a rehash of a pilot called Bits and Pieces which was picked up by Disney Channel but subsequently reformatted into this show. All the cast was exactly the same too, but with Dove Cameron playing a single role and Joey Bragg apparently getting the emphasis. Instead of a twin, the sister would've been played by Cozi Zuehlsdorff who now plays Liv's friend Ocean on the show. The Confession Cam elements are a holdover from the Bits and Pieces pilot, too.
  • Written By Cast Member: Kali Rocha co-wrote "BFF-A-Rooney."
