Sarah Michelle Gellar has vowed she will never return to television - because she found working on Buffy The Vampire Slayer too "exhausting". Gellar starred in the hit show for seven years until 2003, but insists she has no plans to go back to her TV roots because she finds making films far easier. The Grudge actress says, "I don't think I could ever do a one hour programme series again. "It's the most exhausting life. A movie is an hour and 20 minutes and we were filming almost that every week."
