Ex-Buffy stars Sarah Michelle Gellar and Charisma Carpenter are allegedly competing for the lead role in forthcoming superhero movie Wonder Woman.

The actresses - who played Buffy Summers and Cordelia Chase in the hit TV series - are battling for the iconic role after their former boss, Joss Whedon, agreed to direct the movie remake of the 70s television show, reports British newspaper the Daily Record.

An insider says, "Joss has told the studio that Sarah is his first choice followed by Charisma. Sarah expressed an interest, but the producers are more interested in Charisma because she is less well known."
