no, no I did mean Bert Lahr! Bert Lahr replaced the actor (whose name I forget) who originally was going to play the Tin Man..because of the toxic silver make-up. Still can;t recall why Buddy Ebsen was replaced by Ray Bolger. And it is possible the silver make-up thing is an urban legend, i do not have hard fast evidence on that...

thought of another one: Robin Williams in just about anything lately...
