Aaron Eckhart felt awful pretending to be a sad dad at a grief counselling session as he prepared for new film RABBIT HOLE - because other parents there had just lost a child.
Eckhart and Nicole Kidman play the parents of a dead girl in the harrowing film and while the Aussie actress took heed of advice not to attend a real session, the Possession star felt it would be good for his character.
He quickly realised such sessions were not for actors.
Eckhart tells WENN, "It was raw. People had just lost a child the day before. There's a lot of emotion there. I gave my story in the group as my character, which was interesting.
"I only went once and I didn't feel I needed to go back. I thought it was a little unethical and somehow duplicitous."
