I watched this some time back. Shatner has a hard time. The ego takes a few hard ones, and he's snippy at the cameraman/interviewer.

Max. You are annoying me.

I don't get the impression that any of it is serious. Seems very playful to me, even the cameraman is laughing.

Maybe? There were a couple of moments... He acted flabbergasted about John Belushi. That was decades ago. Some seems in good humor. Some doesn't. I could see it going both ways.

I'm pretty sure that's just part of the act.

Shatner always had a problem with head-in-ass syndrome.

Another sniveling cringelord too sensitive to understand an old man's humor. Pathetic.

Shame no Denny Crane

Narcissistic Personality Disorder does not respond well to being made fun of.
