If you do too much acting in a lead part in a feature film where you're 40 ft. high, it's rather unattractive. You can see the acting. And it's actually the right thing to do to bring as much of yourself, I believe, to the part as you possibly can - to minimize the amount of theatrical stuff that you need to do.
When you have kids you just love them. It's similar to when you're in love with someone. You just think they are so cool and want to be around them all the time but what if she starts being embarrassed and only giving me charity visits? I want her to actually want to see me so that's what I'm going for!
