I know it's because he chooses interesting projects, but the last couple films I've seen him in, he's portrayed widowed men dealing with fatherhood.
I had Martian Child on in the background while I ate lunch and did some work today. I intend to sit down and watch again with TFMD and/or the kids. It's a good film, and a character I identify with -- even more so than the character he played in Grace Is Gone. In this case, he plays a widower who was once an outcast child and now makes his living in escapist entertainment, trying to raise a child who is "different" while trying to maintain a career and beginning to find a romantic connection again.
I'm going to check my office for any hidden cameras.
