Bern,
I always expected Ian McKellen to actually be a grey wizard from Middle Earth. I was quite disappointed to find out he is actually a human RSC thesp with no magical powers. It ruined the trilogy for me when I found out, and now I refuse to read the books because none of it smacks me as realistic any more.
. Oh, on that note I saw an interview with Leonard Nimoy the other day and found he doesn't have pointed ears. That's ruined Trek for me too.
Good luck to the musical native Americans, they are good at what they do and always pull a small crowd.
