'Scooby-Doo' star Matthew Lillard to be replaced by Will Forte in upcoming 'Scooby' film

Actor Matthew Lillard just found out he will be replaced in the upcoming “Scooby-Doo” film in the worst way possible.

Appearing in over 30 “Scooby-Doo” productions, Lillard has been a mainstay in the franchise for a decade plus. Known for his role as the goofy slacker Shaggy Rogers, Lillard donned the iconic green shirt and blonde mop on-screen in the early 2000s and succeeded Casey Kasem in the animated “Scooby-Doo” universe after Kasem’s retirement in 2009.

But after Gina Rodriguez, Tracy Morgan, Frank Welker and Will Forte were announced for the first theatrical “Scooby-Doo” production since 2004’s “Scooby-Doo 2: Monsters Unleashed,” Lillard found out through an online report that he was being replaced by Forte.

Finding out through an online report about the casting, Lillard took to Twitter to voice his displeasure. Begrudgingly, Lillard tweeted, “Well this sucks. What a crappy way to find out.... thanks Hollywood. You never sense to amaze me.”

Lillard jokingly acknowledged his grammatical flub in the following tweet, stating, "Cease. Duh."
