While the pair ran the scene, O'Heaney said Kilmer suddenly hit her in the face and pushed her to the ground.
While talking to an entertainment website, Caitlin, noted, "Women have come together, saying, 'We're not going to be f****d by you. finally have the confidence to speak about this. It's too long that I've sat on this story."
Adding, "I went down to my car and I cried for about 20 minutes."
The actress filed a police report a month later.
Bramon Garcia noted that O'Heaney and all other actresses were warned that they would be reading a volatile scene that could result in physical contact.
"It was way blown out of proportion. I am not somebody who takes this stuff lightly. I can tell the difference between something that's abusive and a moment that got carried away, but it was all in the context of the work. [O'Heaney had] a very extreme reaction to a situation that to me was not extreme at all."
However, O'Heaney claims she was so traumatized that she filed a police report after the alleged assault.
The actress ultimately reached a settlement with Kilmer, Stone and Carolco Pictures for USD 24,500.
But O'Heaney says she was left with only about USD 8,000 after taxes. She also signed a non-disclosure agreement, which she says she still regrets. (ANI)
