Conan's somewhat on the tall side, and Shatner is a very short guy.
Angelique Pettijohn told the story of auditioning for "Gamesters Of Triskelion" and after looking at the script saying to the casting director and producer - against her own better interests - that she didn't think she was right for the part. "This character is described as 'an amazon.' Look at me, I'm tiny."
Whereupon the Trek folk laughed and said "honey, you haven't met Shatner - next to him you'll look like an amazon."
Shatner is cool, he's funny, he's a good actor, he's got a strange enough sense of humor to be both intriguing and irritating. I love him. I guess one can't
help being interested in what he thinks of things - but honestly there's not
really a good reason in the world to give a flying fuck what he thinks about
anything, is there?
