Smoking Umbrella: The Penguin In Batman Returns

Batman Returns: This is the best review of the movie I've ever read, hands down.
Batman Returns :: Penguin: Maybe not as entertaining as the last one but a very good fansite for DeVito's Penguin.
Crazy Mofos: Batman Archives: You'll have to scroll down a bit to get to the Penguin - but why do that when you can read the whole page? You'll want to! They're Crazy Mofos!
Batman Returns - The Penguin: A lot of info on the making of the film, specifically on DeVito's performance. Very good.
Batman/Election Returns: A essay relating Batman Returns to...Chitty Chitty Bang-Bang? Yes! Very interesting!
