I've never understood how Nielsen got that big credit at the end, "AND LESLIE NIELSEN AS THE CAPTAIN" as though he was a kind of "special guest star" of sorts.

B. Solid, but really nothing special. Basically anybody could have played that small role.
You've seen Guy Standeven in something because the man was in everything.

I just go….Oh, Leslie Neilsen! Anyone could have played the role, though it is quaint to see Neilsen in the small role, it not even worth pontificating over.
As we know though, the film itself is full of plentiful solid performances. Always a treat to watch TPA.
Norman! What did you put in my tea?

He doesn't really act. He just says his lines. And it's such a short scene, I rarely even think of LN as being in this movie.

"It's kind of a non-performance."

This is my favorite absolute best movie of all time. I’ve seen it over 600 times and I will be watching it again tonight thanks to you Mr. 🪨

He is one of the few actors who did a 180 where first casting directors got him for being super serious to then wanting him to be a total, slapstick funny, silly goofball.
