The Scottish 'Sunday Post' Newspaper has an interview with Sean Bean (Boromir). In it they ask about being away from his family while shooting the LOTR films:

Sean is currently in New Zealand, making three films back to back, with big names such as Ian McKellen, Cate Blanchett, Liv Tyler and Christopher Lee.

“I’m over there on my own right now but I’ll be bringing the family across when we get a break.

“I do miss them, but I’ve always been away for parts of the year. I’ve got used to it and I tend to just focus on what I’m doing, get it done and come home.”

Thanks to Nona for the tip!
