* AccidentallyCorrectWriting: An interview with cast and crew revealed a story that the shows writers were once called into the CIA to find out where they were getting ideas for the show's gadgets. Apparently, a few items in the series were ''suspiciously'' close to actual tools the CIA was developing.
* ChannelHop: From Creator/{{NBC}} to Creator/{{CBS}}, for the fifth and final season.
* DirectedByCastMember: Don Adams directed 13 episodes.
* IronyAsSheIsCast: In contrast to his role as Larrabee, who was often being portrayed as even more bumbling than Max, Robert Karvelas actually worked as a stockbroker before he became an actor, a job that obviously requires a lot of book smarts.
* StarMakingRole: For Don Adams.
* TechnologyMarchesOn: The very first scene of the black-and-white pilot takes place in a crowded theater where Max is sitting in the audience and begins with [[EarlyInstallmentWeirdness a narrator explaining]] how important it is for an agent like Max to remain inconspicuous and not blow his cover by drawing attention to himself... right before Max's shoe phone rings. In such an environment in the 1960s, a phone ringing right in the audience would certainly have drawn a lot of confused stares, but after 2000, you'd come across as rude but not the least bit suspicious.
* ThrowItIn: Don Adams and guest star Don Rickles did so much of this during production of "The Little Black Book" that the episode, written as a one-parter, became a ''two''-parter.
* WhatCouldHaveBeen: Mel Brooks and Buck Henry originally pitched the show to Creator/{{ABC}}, with the intention that Tom Poston play Maxwell Smart. ABC, however, declined. NBC then picked up the show, but requested that Don Adams be cast as Maxwell Smart as he was already under contract with the network. ABC would later green light another show from the same production company, ''Series/SupermarketSweep''.
* WrittenByCastMember: Don Adams wrote two episodes, while David Ketcham, who played Agent 13, wrote an episode.

* ActorAllusion: The opening scene plays the Music/{{ABBA}} song, "Take a Chance On Me". In ''Series/TheOfficeUS'', the song is sung by Andy in a famous scene. Steve Carrell was a main character on that show.
* ApprovalOfGod: Zig-zagged. Mel Brooks gave his blessing for the film and loved Steve Carrell's performance, but still said he couldn't hold a candle to Don Adams.
* TheDanza: Dalip, Siegfried's [[TheBrute brute]], is played by Dalip Singh -- known as The Great Khali of Wrestling/{{WWE}} fame.
* RoleReprisal: The Mexican Spanish dub brought back Jorge Arvizu, who had voiced Max in the classic series.
* ThrowItIn: Anne Hathaway ad-libbed the scene where Agent 99 grills Max on what he would do if confronted by a gun-wielding assassin.
