Buffy The Vampire Slayer

LOS ANGELES (Zap2it.com) - Next week, Freddie Prinze Jr. and his wife, "Buffy the Vampire Slayer" star Sarah Michelle Gellar, are due to head to Vancouver, Canada, to start production on the "Scooby-Doo" sequel.

Work on the film immediately follows the end of production on "Buffy," which is shutting down after seven seasons — five on The WB and the last two on UPN.

Without going into specifics, Prinze hints that the later seasons of "Buffy" may have been rough for his bride.

"A lot of people owe Sarah a lot for doing that show," Prinze says, "and she doesn’t always get the credit she deserves. She’s a very strong woman, because she deals with a lot of nonsense, and instead of that nonsense, she should be thanked — and she’s not. That’s the reason she won’t be coming back."

"Sarah’s the most appreciative person in the world, and if that environment would have remained the way it would six years ago, she would go back, because she’s loyal. But things change, and people’s egos get in the way sometimes. They make poor decisions."

"I don’t agree with it, but I understand it, and I just pray I’m never guilty of it."

Prinze asserts that, whatever happened, Gellar gave 100 percent. "And even if she’s not, nobody knew, because she commits. She’s badass."

The series finale of "Buffy the Vampire Slayer" airs on UPN Tuesday, May 20, at 8 p.m. ET.
