Actress Sarah Michelle Gellar turned down a lead role in Stardust - because she didn't want to be apart from husband Freddie Prinze JR. The Buffy The Vampire Slayer star married Prinze Jr. in 2002 and the couple made a vow to avoid conflicting work schedules so they could spend more time together. But the promise meant Gellar missed out on a part in the new fantasy adventure movie starring Robert De Niro and Michelle Pfeiffer - because the film was being shot in Scotland when Prinze Jr. was filming in the U.S. She explains, "I turned it down because it was Freddie's turn in New York. I would have loved to have done it - are you kidding? But it was Freddie's turn." The couple met during the filming of I Know What You Did Last Summer in 1997 but they didn't begin dating until 2000. They were engaged by April 2001 and married eighteen months later.She has starred alongside her husband in Scooby Doo and the sequel Scoody Doo 2: Monsters Unleashed as well as the couple lending their voices to new movie Happily N'Ever After.Gellar made her name in television starring in Buffy the Vampire Slayer before moving into movies where she has had mediocre success.
