Walken a fine line there Burton!

I’d have thought he’d go straight to Johnny Depp, But none the less seems Tim Burton is after Christopher Walken for his reworking of “Willie Wonka and the Chocolate Factory”. According to Cinescape, Walken [who worked with Burton on “Batman Returns”] has emerged as a frontrunner for the role of the kooky factory head. Anyone else picturing a dark, cola-coloured river of Dr Pepper, and trees adorned with black licorice?
