James Marsters has a lot of good stuff to say about Sarah.
"I think that's screwed" an opinion held by James on Sarah Michelle Gellar being ignored by awards such as the Emmys. He mentioned the episode Triangle after Riley departs, where Sarah Michelle Gellar must cry, but in a comical way throughout the episode. You may recall critics complaining about her ability in those scenes - saying that it was 'bad' acting. "Do you watch Party of Five?" (A collective groan resonated from the audience) James explained that if Jennifer Love Hewitt was to do the crying even half as good as Sarah Michelle Gellar did in those scenes, but on Party of Five, the world would come to a stand still, people would be raving positively about it for weeks.
James truly has nothing but admiration for Sarah, "She's taught me a lot, I love her to death" James gave an example of her talent - in the crossover episode 'I will Remember You', when Buffy and Angel's day is about to be taken away from them, when she is crying, he believes that, as an actress, "In that moment she became beautiful, she was real."
