Sarah Michelle Gellar talks TV return at Comic-Con

(CBS/AP) - Actress Sarah Michelle Gellar took the stage at Comic-Con Thursday to talk about her big return to television in The CW's "Ringer."

The former "Buffy the Vampire Slayer" said during a panel that she was drawn to the new serialized thriller because it wasn't like the supernatural series that she starred in for seven seasons.

"It's the first time in a very long time in which I was surprised by something," Gellar said, according to The Hollywood Reporter.

"I knew I wanted to come back to television," she adds.

In "Ringer," which debuts Sept. 13, Gellar plays mysterious estranged twins Bridget and Siobahn. It also stars Nestor Carbonell, Ioan Gruffudd, and Kristoffer Polaha.

The 34-year-old actress said she feels like she's actually playing five characters in "Ringer": Bridget and Siobhan in the present, in the past and Bridget pretending to be Siobhan, which she dubbed "Siovette."

But fans shouldn't expect any "Buffy"-style antics.

"There will be no demons, no vampires and nothing supernatural," executive producer Nicole Snyder informed fans. "Sorry, guys."

It's not the first time Gellar has played opposite herself. She appeared as a robot Buffy in the fifth season. Gellar said "Ringer" scenes featuring both twins will be filmed using techniques like a body double and computer-generated effects.

"I think by season three, they'll clone me," joked Gellar.
