Sarah Michelle Gellar was so shocked by how realistically violent co-star Andy Garcia was while shooting scenes for their new movie, she had to walk off set.

The actress grew close to Garcia while they made The Air That I Breathe together - but found it hard to watch his method approach to his role as a crime boss.

Gellar battled through scenes when Garcia was forced to beat up their co-star Brendan Fraser's gangster, and suffered herself when he turned on her character, a pop star.

She says, "I had a hard time separating the scene from what is reality. And at one point I had to leave. I didn't know the scary side of Andy. I'm a small girl, and he doesn't let go. When he throws me up against a wall - that's actuality."
