LOS ANGELES (Zap2it.com) — Shaggy guy Matthew Lillard says he doubts a "Scooby-Doo 3" will happen. "The second ’Scooby’ didn’t do as well as it was expected to do, and I completely hold Warner Brothers at fault because of the time they released it," Lillard tells Zap2it.com in an interview for his upcoming film "Without a Paddle."

"Scooby-Doo 2: Monsters Unleashed" opened to $29 million when it debuted last March 26 which pales to the $54 million opening weekend of the original "Scooby-Doo" in summer of 2002. "Scooby 2" has made about $84 million so far, compared to the first film’s $153 mil.

"I think the movie’s much better than the first movie, and I honestly thought it was going to do ridiculously good box office, but we had a bad time slot," Lillard says. "We had 13 movies open up in two weeks after we opened up."

The sequel also was released around the time of "Hellboy," "Dawn of the Dead," "Home on the Range" and "The Passion of the Christ."

Lillard also hints he’s tired of playing the goofy sidekick, like he has done for four films so far with his friend Freddie Prinze Jr. He says Prinze and wife Sarah Michelle Gellar never had any intention of reprising their roles as Fred and Daphne, although Lillard would have played Shaggy again.

"We didn’t really need them, we could have done it without them," says Lillard.

Director of the past two "Scoobys," Raja Gosnell says he hoped the next movie installment would take the Mystery Van team to London for their next ghost-busting adventure.
