I have always been a massive DiVito fan especially his Penguin man, he and walken do such a great job of playing devious characters, i was truly disturbed by his (penguin man) death at the end of the film.
and the little penguins look so sad
But from the comic book i like the character 'Clay Face' he is essentially a living version of the 'incredible melting man' only he doesn;t die... well he has died a few times but new people have teken on his DNA and so they also being to drip and are able to change thier appearance to anythingt hey like to foil the Bat! If you ever get to read Arkham Asylum by Grant Morrison you will get to meet Clay Face.
