Having never seen Broke-His-Back Mountain or any other body of work by these people, I got fed up when reading that "Zodiac" did poorly at the box office so far, and wondered how two siblings seemed to burst on the Hollywood scene all at once. Something I don't follow, but I'd never heard of these two until recently. Round up the usual suspects. Aww jeez, how touching - according to Wikipedia, their parents are in the biz. How many better actors have been excluded from nice parts by this family alone?? More reason not to patronize the LA-LA land agenda....
