Little known fact. James Gunn wrote the screenplay for Scooby-Doo: The Movie. A movie I quite enjoyed when I was growing up and still to this day. I was in California on vacation when I saw it with my family. I really thought it was clever to make Scrappy Doo the villain because so many people hated him in the original series. I also thought the casting was so enjoyable. Sarah Michelle Gellar, Linda Cardellini, Freddie Prinze Jr, Isla Fisher, and Matthew Lillard were so great to watch re-enact my favorite cartoon characters. It was a kids movie sure, but at fifteen years old I still thought it was funny and cool in its own right. 

Well, James Gunn had a lot of fun being involved in writing it, and got to be on set with the actors during the filming and he has very fond memories. In honor of the 15th anniversary,...
