Sarah Michelle Gellar was really surprised to know that 'Buffy the Vampire Slayer' was celebrating its 10th anniversary.
The show ended 10 years ago on May 20, 2003.
Series star Gellar is returning to TV opposite Robin Williams with 'The Crazy Ones,' a new comedy on CBS this fall.
At the CBS 2013 upfront red carpet last week, Gellar was surprised by how much time has passed since she last wielded a wooden stake on TV, the Huffington Post reported.
"I'm incredibly proud of that show-proud of everybody on it, of what we did ... You can't be prouder of that show. It still holds up in reruns and I'm blessed every day ... I've been pretty lucky," she said.
'Buffy the Vampire Slayer' lives on in comic book form with new adventures from Dark Horse Comics executive produced by series creator Joss Whedon.
