When my career first began, I didn't have children - so there's a whole lot of difference in the way I choose roles now. Not just films for my children, but how long I'm going to be away, and is Dad going to be home while I'm gone. That sort-of factor plays a part.
To be honest with you, I get a little fed up with actors who act crazy to make themselves more interesting.
Scratch the surface of what's socially normal. I suppose in some way all of us have something we display to the public and things we feel too ashamed of or uncomfortable with to reveal to other people.
