He had a small, but memorable role in his first film, In the Heat of the Night, but it was his second movie, In Cold Blood, that really made people notice his talents. As the heartless killer, Dick Hickok, Wilson's performance is as scary as any film villain in the history of motion pictures.
Scott Wilson is truly one of the best actors the world has NEVER heard of. Check out his credits on IMDB and then watch some of his films. You'll be amazed at what you see.
