* CreatorBacklash: This game was ''birthed'' by it! In an interview in the ''Star Fox 64'' Nintendo Player's guide, Creator/ShigeruMiyamoto said he had never been happy with the visuals of the original [=SNES=] ''Star Fox'', and that dissatisfaction was the primary impetus to remake it as ''Star Fox 64''.
* KillerApp: For the Platform/Nintendo64. It had voice acting (Peach and Mario in ''VideoGame/SuperMario64'' had a few lines, but this was the first N64 game to be fully voiced) and controller vibration via the Rumble Pak, which it came packaged with.
* TheOriginalDarrin:
** After being replaced by Steve Malpass for ''Adventures'' and Jim Walker for ''Assault'', Mike West returned to voice Fox in ''Star Fox 64 3D''.
** Lyssa Browne also returns as Slippy in ''3D'' after being replaced by Chris Seavor for ''Adventures'' and Mike [=McAuliffe=] for ''Assault''.
* TheOtherDarrin:
** Due to the tragic suicide of Creator/DaisukeGori in 2010, all of the original Japanese cast for ''Star Fox 64'' was replaced, beginning with ''3D''.
** In the English version of ''Star Fox 64 3D'', everyone besides Mike West (Fox and James), Lyssa Browne (Slippy and Katt), David Frederick White (General Pepper, Pigma, and ROB 64) and Ja Green (Leon and some other voices) were recast.
* TheOtherMarty: The game's developers originally voiced the characters, but were eventually recast with professional voice actors.
* UnspecifiedRoleCredit: The cast section in the game's ending credits lists the voice actors, but not their roles. The English voice actors' roles were [[http://geekmelee.com/2016/04/star-fox-64-the-voices-that-echo-through-the-lylat-system/ eventually confirmed]] in April 2016.
* WhatCouldHaveBeen:
** The walker from ''VideoGame/StarFox2'' was intended to be added, but was cut because it wasn't enjoyable to use and broke the pace of the game. Miyamoto responded to this by having the Landmaster and Blue Marine be added instead, with the latter being planned for more levels than just Aquas.
** The code for the "[[SpeakingSimlish Lylat Language]]" mode was created early in development just in case having fully-voiced dialogue proved infeasible from a cartridge space standpoint, and DummiedOut from the North American and Japanese releases due to the developers thinking that nobody would choose to use it over actual spoken dialogue. It was re-instated for the European ''Lylat Wars'' release, possibly due to the infeasibility of creating different dubs for every additional country that the game would be released in (France, Germany, Italy and Spain, specifically).
** The Japanese voice acting was originally recorded [[http://shmuplations.com/starfoxadventures/ by the developers themselves]] until they were told it was terrible and the dub was re-recorded with professional actors.
** The Nintendo source code leak in 2020 revealed that early builds of the game featured remixes of some of the music tracks from the first SNES game, evidently before the decision was made to go with an entirely new soundtrack.
* WorkingTitle: The 2020 Nintendo leak revealed that in the early stages of development, the game was called ''Star Fox: The Cosmic Crisis''.
