* ActorAllusion:
** Nathan Lane is openly gay.[[note]]Though he wasn't out at the time the movie was released.[[/note]]
*** He also plays a guy who [[Disney/TheLionKing dresses in drag (he doesn't do the hula, though)]].
** Robin Williams dips into his trademark Creator/JohnWayne impression at one point.
** The dancer whom Armand instructs to do an "eccentric celebration of dance" is told to do, among others, "Madonna! Madonna! Madonna!" The actor playing him was, in fact, a former backup dancer for Madonna.
* DawsonCasting: 32-year-old Calista Flockhart unconvincingly plays a 19-year-old. (Being so waifish, she could pass as a senior or graduate student, but come on.)
** Dan Futterman was 27, playing the 20 year old Val.
* GeniusBonus: Senator Keeley calls Grover's Corners "a darn good place to call home", apparently unaware that the play it's featured in, ''Theatre/OurTown'', was written by a gay man.
* HarpoDoesSomethingFunny: Due to the nature of the story, Mike Nichols made Nathan Lane and Robin Williams ''promise'' to do one take exactly as scripted before they could go wild in retakes. This is bound to happen.
* PlayingAgainstType: One of Creator/RobinWilliams' few comedic roles as the (no pun intended) StraightMan. In fact, he was originally cast as Albert before he asked to switch roles with Nathan Lane in fear of TypeCasting.
* ThrowItIn
** Robin Williams' pratfall in the kitchen was entirely accidental, but the other actors [[{{corpsing}} held it together]] enough to use the take.
** Director Mike Nichols added "...but you keep it all inside" to the end of Armand's "eccentric celebration of dance."
* WhatCouldHaveBeen: Before he had to drop out due to scheduling conflicts, Steve Martin was set to play Armand, with Robin Williams as Albert.
