Oz actor on reuniting with Sarah Michelle Gellar for Scooby Doo 2.

Actor Seth Green, who played teen wolf Oz over three seasons of Buffy has been talking up his latest film role.

Green is once again sharing a screen with Buffy co-star Sarah Michelle Gellar in the forthcoming movie Scooby Doo 2: Monsters Unleashed.

He plays Patrick, the curator of a museum housing the costumes of the ghosts and monsters that the Mystery Inc gang have unmasked. When a bad guy steals the costumes and starts bringing them to life, the curator is a prime suspect.

Green recently spoke about his new role to About.com. Asked if he found it different working with Sarah Michelle Gellar on Scooby-Doo 2 than on Buffy, he said.

"In the last few years with her getting married and her getting a real sense of comfort with who she is as a person, she's much happier. She just seems to radiate a sense of comfort in her own skin and that's great.

"I've known her since I was nine years old and I have the utmost respect and admiration for her. I think she's a really talented actress. I think she's handled herself very gracefully through everything that she's had to experience in the last six or seven years. It was great. It was really nice to see her."

His friendship with Gellar and other members of the cast also made it easy to slot into the role of Patrick.

"It makes a huge difference because there's a lot of guesswork taken out," he said. "I've known Sarah forever and I was in Freddie's first movie. Linda I was a fan of but had never met before and Matthew and I have known each other in passing. But, I've always wanted to work with him. I was really excited because the first few scenes I got to work with him set the tone right off."
