Washington, Jan 31 (ANI): Actress Sarah Michelle Gellar has revealed that she was shocked with the realistic aggression co-star Andy Garcia displayed while filming their new movie.

Gellar said that Garcia's anger was so real that she had to walk off the set.

The actress had grown really close to Garcia while they were making the movie 'The Air That I Breathe', but she found it very hard to watch the way he acted out his role as a crime boss.

Gellar had to battle through scenes when Garcia was forced to beat up their co-star Brendan Fraser's gangster, and suffered herself when it was turn for her character as a pop star, to get bashed up.

"I had a hard time separating the scene from what is reality. And at one point I had to leave," Contactmusic quoted her as saying.

"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," she added. (ANI)
