* ActorAllusion: One for Creator/MelBrooks: he has his profession written on the back of his suit, which he's done in many of his films before (''Film/BlazingSaddles'') and since.
* AllStarCast: Between the Muppets themselves and all the cameos...
** Including, behind the scenes, Creator/TimBurton and Creator/JohnLandis, who were amongst the numerous people called in to operate the Muppets for the final number.
* HeyItsThatGuy: Of course there are lots of cameos, but among the major human parts...
** [[OBrotherWhereArtThou Governor O'Daniel]] is running a line of frog leg restaurants!
** Max went on to head [[Film/ShortCircuit Nova Robotics]].
* HeyItsThatVoice: Max later appeared in ''WesternAnimation/FindingNemo'' as one of the tank fish, Gurgle (the one who's obsessed with cleanliness).
* RealitySubtext: Edgar Bergen and Charlie [=McCarthy=] made their last appearance in the film - Henson was inspired to make the Muppets because of him. Bergen died not long after his scene was shot, and the film is dedicated to him.
* TalkingToHimself: One of the benefits of this and the other feature films was the opportunity it afforded for characters like Jim Henson's Kermit and Rowlf, Frank Oz's Piggy and Fozzie, etc., to interact in a way that wasn't always technically feasible on television.
* WhatCouldHaveBeen: [[http://www.toughpigs.com/anthmovie01.htm Visit here for an analysis on a draft script]], but the biggest one to note is the recurring appearance of '''Henry Kissinger''', whose entire schtick is that he's not cast in the movie, not even for the Framing Device. Hilarious in Hindsight again?
** Henson wanted Hopper to have a HeelFaceTurn, but Frank Oz disagreed, and won out.
