Sarah Michelle Gellar

Sarah Michelle Gellar has spoken about her role in upcoming sci-fi thriller Southland Tales.

The former Buffy the Vampire Slayer star is thrilled to be working with director Richard Kelly, who she describes as a "free-thinker".

"I think, unfortunately now, Hollywood and movie-making has become incredibly formulaic," Gellar explained. "Richard does the exact opposite. Whether it’s casting or story ideas or camera shots, it’s about doing something that’s different. And I think, as an actor, what’s enticing and why he can always get such amazing casts of people is because of the excitement of the unknown, of doing something that hasn’t been done.

“I think if Richard told me that his next project was going to be a rendition of the Yellow Pages, I probably would be the first one signed on for ‘N’ through ‘T’.

“I think that he’s so open and he has so many great ideas and he’s willing to try anything. And if it doesn’t work, he moves on. He’s not married to anything. It was a lot of improv. On the day [of shooting], he’s constantly coming up with not just new lines, but incredibly huge, new scenes.”
