"Joss and I always talk about [a movie]," Gellar told E! News, referring to the franchise's creator, Joss Whedon.
"But the thing with Buffy is that Buffy was a movie, and it ultimately didn't work as a film. And I mean, we had such miles to overcome when we were trying to do a TV show based on a movie. And one of the reasons is that the story works better over time," she said. "If there was ever the right story, we would do it. ... At this point, the stake would be my walker and I would be hobbling in."
Gellar, 36, played the character on the critically acclaimed action-drama "Buffy the Vampire Slayer" for seven seasons from 1997 to 2003. The series spawned the spinoff show "Angel," as well as numerous "Buffy" comic books and novels.
Kristy Swanson played the role in a 1992 film version Whedon wrote, also called "Buffy the Vampire Slayer."
Gellar will soon be seen starring opposite Robin Williams in the CBS sitcom "The Crazy Ones."
