Who Am I?

I was born in in Los Angeles, Ca, a only child....as a child, I liked baseball cards and comic books....
I was very close to my Russian grandmother who I called "Oma" she passed away in German at the age of 93 in 2008....and I visited her often in her later years..

I first started in commercials and my first break was in a TV show that was shortlived based on the Parenthood movie.....I went on to do small roles in "The New Lassie" and "Roseanne". I got to work with Robert DeNiro, and Helen Barkin in my first big movie. I got an academy award for my next movie, and a Golden Globe in 1993....

I am unmarried and in my spare time, I work on environmental issues....
