"I bring it home with me, and that's why I count down the days until the end of production so then I can move on with my life," said Wahlberg. "But knowing that I'm going to have to just go back there the next morning, no, I can't turn it off."
Wahlberg needed to walk in his character's shoes until his work was done. He found himself giving his own children extra hugs.
"Oh, squeezing them like crazy," said Wahlberg. "They didn't know what was going on, why daddy was crying all the time, but that's what it was, you know, and I was -- part of me was reluctant to go to that place."
One reason Wahlberg did take this role was for the chance to work with director Peter Jackson of "Lord of the Rings" fame. But he decided not to read the novel.
"And you start wondering, why this is in there, and why something else was left out, and the script was very moving, very emotional, very powerful, so I felt like there was no need to read the book," said Wahlberg. "And my wife had already read the book and loved it and read the script and loved it."
"The Lovely Bones" also stars Rachel Weisz, Saoirse Ronan, Stanley Tucci and Susan Sarandon.
