Sarah Michelle Gellar, the American actress best known for appearing in the long running drama series 'Buffy The Vampire Slayer', could return to television to play twin sisters in a new CBS show titled 'Ringer', reports Entertainment Weekly. The show is currently in development and a pilot episode is expected to be filmed in May.

Although Gellar has been cast in the show, the drama is yet to be commissioned and a decision will be made after the pilot episode airs later this year. The actress was expected to appear in the much-anticipated HBO series 'The Wonderful Maladys', but the show never made it past the pilot stage. Producer PETER TRAUGOTT confirmed that the "edgy thriller" will follow the story of two twin sisters who grow apart over a tragedy in their past. He also confirmed that Gellar would play the role of both twin sisters and added, "The sister who is seeking redemption has had a much more troubled life. When her fancy pants sister disappears, she takes over her life. She's living the life of her more successful sister".

The actress has struggled to land major roles since leaving 'Buffy' and her last television role came when she voiced a character on the animated series "American Dad' last year. In 2009, she appeared in the straight-to-dvd movie titled 'Veronika Decides to Die'.
