The actress revealed that both characters she plays on Ringer are completely different to Buffy Summers.
"She's not saving the world, she's just trying to save herself," Gellar told IGN, regarding her main character Bridget. "I do get to hold a gun a lot on this show. Which is cool because Buffy never got to hold a gun."
"I never had any time," she explained, when asked why she stayed off television after Buffy. "After it was over, I sort of needed to explore and live that gypsy lifestyle and travel the world."
Despite feeling burnt out by the time the popular show came to an end, Gellar also said that she is still happy to be so closely associated with the character.
"I'm proud of the show. I'm proud of the work we did and I'm proud of the legacy," she added. "And if people think I can save the world and kick butt then I'm okay with that."
Gellar recently confirmed that she will return for a one-off guest appearance on All My Children, following the show's recent cancellation.
Ringer is due to premiere on September 13 at 9pm on The CW.
