I never saw James Woods in a film before the Onion Field. To this day I have never forgotten his performance. Whenever I see him, I think of The Onion Field. He often is cast as the bad guy, and he usually pulls it off very well. He was excellently bad in Once Upon a Time in America, The Getaway, Ghosts of Mississippi, Casino, and others. The Onion Field was, however, absolutely a masterpiece performance by Woods. Greg Powell was an evil person, and Woods nails the role. This film does not seem to be on TV often any more, but is worth looking for. It is truly chilling.
