One more time. Today Matthew Lillard, who played Maniac in the WC Movie turns thirty-one years old. This year he'll be starring as the one and only Shaggy in the upcoming live action Scooby Doo movie by the way.. And according to IMDB, Freddie Prinze Jr, Blair from the movie, is gonna be Fred. That's freaky. Think that's it? Nope. They're also both starring in Summer Catch this year too. The world never ceases to amaze me.
