Scooby Doo co-stars want to make sequel

Matthew Lillard and Freddie Prinze Jr say they want to make a sequel to the forthcoming Scooby Doo movie.

The film hasn't even been released yet.

They say they had such fun working on the first movie that they would love to do a second.

Scooby Doo will also star Sarah Michelle Gellar and Rowan Atkinson.

Lillard, who admits to having some nerves about his role in the film, said: "Playing Shaggy was scary. I mean, playing a guy that is so iconic. Scooby Doo is the number one international cartoon. It has been for like 10 years".

"We had a blast on the set the movie is going to be great, it's hysterical and we want to do a second Scooby movie," said Prinze Jr. "We hope it's a hit at the box office and I am glad that I picked this movie."

Scooby Doo is due to be released next year.
