Reanimator's Herbert West (Score 2, Interesting)

I've always had a soft spot for the mad/obsessed scientist, and Jeffery Combs does a fantastic job as Herbert West in the Reanimiator films. Aside from being devoted enough to his work to kill (and reanimate) obstacles, he just can't pass up a "what if" experiment when it presents itself. From the very beginning, his curiosity is what killed the cat, reanimated it, and killed it again.
