United Kingdom, Jan. 26 -- Sarah Michelle Gellar thinks she's too old to play Buffy the Vampire Slayer again.

The 47-year-old actress shot to fame portraying Buffy Summers in the hit TV series - which ran from 1997 until 2003 - and despite rumours of a reboot, she thinks producers will want to cast a younger star in the lead role.

"I don't know if I would approach playing her any differently. Buffy is such a beautiful character - that never changes.

"If people think I can still save the world and kick butt, I'm OK with that." ...
