Retrieved May 30, 2012. Hey Matt, loved you in Scream. I heard that Scooby-Doo was originally scripted and shot as a much more adult-oriented movie, but then got edited to be more family friendly. If that's true, any chance you could give some details on the stuff that got cut out? u/matthewlillard gladly answer. It was after the heat of SHREK and the studio was all for a above the kids head line of comedy... they brought in James Gunn (SUPER? SLITHER? He's the best ever, love him) and he delivered that version of the script. Yes to all the things you think it is. Smokey van. Velma eyeballing Daphne. Fred being gay because of the ascot. When we tested the parents flipped their lids and Warners got scarred. Its' one of the crown jewels in their library and couldn't risk a back lash. also the demons were really scarry... they were softened."
