I haven’t seen this officially reported anywhere, so I thought I’d pass along word that Jimmy Fallon has been cast in Drew Barrymore’s directorial debut Whip It! Fallon has been spotted by /Film sources on set of the roller derby dramedy playing “Hot Tub Johnny”, a cheesy hungover announcer who makes nasty comments to all the skaters.My sources have also spotted Andrew Wilson, brother of of Owen and Luke (fans of Wes Anderson know as “Future Man” in Bottle Rocket), who is playing a roller derby coach. The film stars Ellen Page as “an indie-rock loving misfit” who finds a way of dealing with her small-town misery after she discovers a roller derby league in nearby Austin Texas. Whip It! is currently in production.
