Well, it would have to be somebody of the ilk of Sir Alec Guiness, John Houston or Charlton Heston!
Only an actor with such epic credentials could get near the role!

Or, maybe one of the young bucks? Johny Depp would be an obvious choice as he knows where the Island is!!

I have not yet met the great man (maybe this year?) but his exploits in here and on has multi faceted website tell it all....
