When I watch my kids, and I see the primal level at which the sibling relationships are formed, then I completely understand what these unresolved adult sibling problems are based on. You know, 'Mom liked you better' and, 'You got your own room and I didn't.'
I didn't do a movie until I was almost 30. I'm grateful for that because it gave me a chance to be an adult in the world and do work in the regional theater that very few people cared about. I loved it and I wanted to do that stuff.
