Jason Nesmith: You WILL go out there.
Sir Alexander Dane: I won't and nothing you say will make me.
Jason Nesmith: The Show Must Go On.
Sir Alexander Dane: ...Damn you."... By Grabthar's hammer... what a savings."
It's like he's contemplating his entire acting career and questioning how he got to this point in his life.
That's my favorite Rickman scene as well.
It takes a fine actor to pack 30 years of fictional history into a single line. I'll greatly miss his tremendous talents.
Rickman clealy had a lot of fun playing villains; apparently he improvised or re-wrote most of his lines in Robin Hood, making it hilarious.
No, it's Leonard Nimoy. This is a Trek TOS satire, and he's the alien sidekick who hates his catchphrase "Live Long and Prosper" or, in this case, "By Grabthar's Hammer, you shall be avenged".
Nimoy had a reputation for being quite sick of being Spock. It was even the title of his biography: https://en.wikipedia.org/wiki/I_Am_Not_Spock
But on the other hand, that might just be an oldish man not really feeling comfortable playing an immature character (that's part of Han's charm, really).
I'd wager his dislike of the Han Solo character had more to do with working with George Lucas.
(Jason is fighting the rock monster)
Jason: Alexander, you're supposed to be my adviser, advise me!
Alexander: Well, you're just going to have to figure out what it wants. What is its motivation?
Jason: It's a rock monster, it doesn't *have* any motivation!
Alexander: Well, there's your problem, Jason, you were never serious about the craft!
