NICOLE Kidman sent Aaron Eckhart a text message to ask him if he wanted to star in her new movie Rabbit Hole.

The Batman star admits he was initially surprised to hear from the Aussie actress — but was delighted to take on the role.

“I’m not sure how that happens,” he said. “I’m still pretty naïve about that stuff. I don’t mean to be cynical about this, but I know that in most cases, a lot of names get discussed before they wind up at your name.

“In this case, I got a text that said that Nicole Kidman wanted to talk to me. I sent a text back: What did I do wrong?’

“Nicole and I are with the same agency. Her agent talks to my agent and sets up the call. It’s so regular, it’s boring.

“I was in Puerto Rico doing the movie with Johnny Depp which was a blast. Anyway, Nicole called and she was serious. She has skin in the game.

“It means she’s invested in the project. She has something to lose or gain in the project. When you get a call like that, you know that they want this to happen. It means a lot. It tips the scales for me.”
