Aaron Eckhart was on Conan last night, December 20, 2010 where he spoke about surfing, filming Rabbit Hole, Nicole Kidman and much more!!

Eckhart spoke to E! news and revealed that while filming Rabbit Hole there were times they argued.   Making the film about a couple grieving the death of their son took its toll on their tempers. He said:

“She was irritated with me and I was irritated with her but that’s the way movie-making is. 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.”
