How bout western villian. I have two. Bruice Dern in The Cowboys, shooting John Wayne in the back. I think that role actually hurt his career. Henry Fonda in Once Upon a Time in the Old West is just creepy.
Best sports character is Matthew Modine as Louden Swain in Vision Quest the greatest wrestling movie ever made.
I wouldn't even put Clapton in the top 5 for guitar players. To me a great guitar player has his own distinctive stlye that you can instantly tell is his. Clapton is great technically, but not real distictive. IMO he hasn't done anything real great since about 1972. Hendrix, SRV, EVH, Page, Slash even Prince all are or where great technically, but also had there own sound. Clapton, Jeff Beck, Alex Lifeson, all are great, but nothing distictive IMO.
Neal Peart is the greatest drummer because he can do things that most drummers can't. Kieth Moon was great because he was so unique in his sound and playing style. John Bohnam was great because he was so heavy. He really defined Led Zeps sound for me.
