In the midst of all the Oscar chatter surrounding the soon-to-be-released drama film, 'Rabbit Hole,' Aaron Eckhart revealed that it wasn't all fun and games on the set. In the movie, Eckhart and Nicole Kidman play parents who are dealing with the sudden death of their young son.

The 'Dark Knight' actor reveals things got a little tense while the two were filming a pivotal--and emotional--scene of the movie.

"She was irritated with me and I was irritated with her but that's the way movie-making is," Eckhart told E!Online.com. "For one day, are we not allowed? For half a day even? It's so surprising to me when people are surprised that movie making is sometimes tense and uncomfortable because inherently it's going to be."

"You're around tens of people or hundreds of people working on things that are imaginary and that come from the soul," he continued. "You could be dealing with subject matter like prostitution, death, drugs, blah, blah, blah. How could you expect that not to be uncomfortable?"
