He is one of my favorite actors and was known for playing my favorite movie villain, Judge Doom, in Who Framed Roger Rabbit.
I remember that movie since I was a kid. That's how I think Doom is my favorite villain. In that movie, he is a judge trying to kill Roger Rabbit for killing Maroon. In order to do that, he uses the Dip, a concoction used to kill Toons. I watched the part where he killed a Toon shoe. Later, in the Acme warehouse, he plans to erase Toontown with the Dip. Doom gets into a fight with Valiant where he is revealed to be a Toon. When Doom reveals himself as a Toon with red eyes and squeaky voice, Valiant recognizes him to be his brother's murderer. Doom is destroyed by the Dip in the end.
