If Bunny Maloney ever got a movie adaptation, they'd probably cast a celebrity who can do a convincing New York accent for Bunny, like Danny DeVito, or even Chris Pratt doing his Mario voice.

Kristen Wiig would voice Candy.

I don't know who'd voice Jean-François or Charlotte, though.

Oh, and they'd probably name it something simple like The Bunny Maloney Movie, like with Super Mario Bros. or Garfield.
