Another actor who was known to multiple generations for different things - and to all of them for just how much scenery he chewed while doing it. The Rocky Horror Picture Show is a classic that will live for generations to come and for me, his turn in The Wild Thornberrys was also great.
(I don't recall if I saw him on stage in Spamalot. I don't think I did.)
He'd rather reduced his presence in recent years due to health problems, it being a pity we didn't have more of his considerable talent.
What we had though is going to be long remembered.
Rest in peace, legend.
