Nicole Kidman ‘irritated’ Rabbit Hole co-star

Nicole Kidman and Aaron Eckhart irritated each other while filming their new movie.

The pair portray a couple who struggle to cope with the death of their son in a road accident in the big-screen adaptation of stage play 'Rabbit Hole' and Aaron is surprised that people expect them to remain in good spirits while working with difficult subject material.

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.

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

However despite their difficulties Aaron revealed he loved working with Nicole, even though he signed up to the movie without speaking to Nicole in person because his movie ‘The Rum Diary’ with Johnny Depp exceeded its shooting schedule,

He told E! Online: "’Rum Diary’ went over two weeks. We had terrible weather. So Johnny put me on his plane and flew me to New York. The next day I was in rehearsals and the next week we were shooting."

‘Rabbit Hole’ - directed by 'Hedwig and the Angry Inch' filmmaker John Cameron Mitchell - deals with how the couple cope after the driver of the car that killed their child contacts them seeking closure from the incident.
