Gellar said during a panel Thursday at Comic-Con that she was drawn to the new serialized CW thriller because it wasn't like the supernatural series that she starred in for seven seasons. In "Ringer," which debuts Sept. 13, Gellar plays mysterious estranged twins Bridget and Siobahn.
"I knew I wanted to come back to television," said Gellar.
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." Fans shouldn't expect any "Buffy"-style antics though.
"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.
