Just did a rewatch. Absolutely everyone is exactly who they need to be for the story to make sense. I've been aware awhile that Billy Crystal basically ad-libbed for several years, but everyone else, well, they needed to be there.

I first watched it on a TV rolled out in ... what, 1987? I was at choir camp and thought it was on the level of "Mary Poppins" with it being years old. To learn that it had just come out was surprising.

And of course, that made "House of Cards" far more interesting to watch. Robin (I'm intentionally skipping her last name here, as it could be misconstrued) being just as shifty as Spacey has pretty amazing, and knowing she's had that range as opposed to Cary Elwes who plays the same guy every time has been fun to watch.
