* ActorAllusion:
** In ''Star Wars: The Complete Saga'' and ''Indiana Jones: The Original Adventures'', Creator/HarrisonFord's respective characters from each game appear as a GuestFighter in the other.
** The German pilot who fights Indiana Jones in ''Raiders of the Lost Ark'' is played by the same guy who plays the guy who operates the gong in ''Temple of Doom'' (the late Pat Roach). In the LEGO version, the German pilot ''is'' the guy who operates the gong.
** In ''LEGO Indy 2'', the title character is distracted while driving through the warehouse by the sight of you-know-who frozen in carbonite.
** The "Shoot First" achievement for killing Greedo can be done with either Han or Indy.
** [[Film/TheMatrix Agent Smith]] behind [[Creator/HugoWeaving Elrond]] anyone?
** The Achievement for beating Palpatine with [[Creator/SamuelLJackson Mace Windu]] is [[Film/PulpFiction Did I Break Your Concentration?]]
** ''Marvel Super Heroes'' includes a trophy called "Don't I Know You?" for playing as [[Creator/ChrisEvans Captain America and Human Torch]] in co-op.
** In ''Marvel Super Heroes'':
-->"[[Creator/SamuelLJackson Commander Fury]] said to [[SnakesOnAPlane get these]] ''[[{{Bowdlerization}} goshdarn]]'' [[SnakesOnAPlane snakes off this]] ''[[GoshDarnItToHeck goshdarn]]'' Helicarrier!"
** Also, at one point Fury is shown eating a cheeseburger during a meeting with his superiors. No doubt it's a [[PulpFiction tasty Royale with cheese...]]
** Upon completing one of the bonus levels, Fury also says an altered version of the Ezekiel 25:17 speech from ''PulpFiction''.
* AdaptationalBadass: In some games, most (if not at least some) characters that never fought in their source material become capable of kicking some major plastic butt. Particularly in ''LEGO Indiana Jones''.
** One specific case is the Mark 42 Armour from Iron Man 3. In the movies the Mk42 was dozens of upgrades after armors that shrugged off tank fire and could give the thunder god Thor a decent fight, it yet malfunctioned a lot and ''constantly'' fell apart. Here, despite being made of Lego, it never falls apart and is a straight upgrade over Tony's older suits with a fully working arsenal. It not only works, but Tony mentions that he even de-magnetized it so it was immune to Magneto's powers.
* CastingGag: Roger Craig Smith reprises his role of Captain America, but also voices Human Torch. Both are played by ChrisEvans in [[Film/FantasticFour their respective]] [[MarvelCinematicUniverse films franchises]].
* FandomNod: In the "Raiders of the Lost Ark" hub in ''Lego Indiana Jones 2'', we see a pig being roasted. It's not the official LEGO pig, but rather one made by [[http://www.brickforge.com/store/product.php?productid=16468&cat=304&page=1 BrickForge]].

* TheOtherDarrin: In most games, the roles aren't done by the original actors, but ''Clone Wars'' is an exception, being one of the first games to get the cast from the source (in this case, the show) to voice for the game, they even got Creator/JamesEarlJones to do some voice clips for [[SecretCharacter Darth Vader]].
* PlayingAgainstType:
** In the first LEGO Batman, Creator/SteveBlum portrays Batman, Killer Croc (a role he would play without the Simlish in [[VideoGame/BatmanArkhamAsylum another game]]), the Joker, Two-Face, and, of all characters, [[ButtMonkey Killer Moth]].
** Creator/JohnDiMaggio as Galactus.
* RecycledScript: LEGO Marvel seems to take a lot from the first season of ''TheSuperHeroSquadShow'': a cosmic object has broken and been scattered, so the heroes, based in the Helicarrier, must collect the pieces before SelfDemonstrating/DoctorDoom and his army of villains, all ending in Galactus attacking Earth and the two sides forming an EnemyMine to stop him.
* WhatCouldHaveBeen
** Some files for the original ''LEGO Star Wars'' game shows that Zam Wessel was planned to be in the game, as well as a wheelbike chase with Grievous. They brought Zam back for ''The Complete Saga'', but never used the wheelbike chase, presumably due to already having a driving segment.
** Similarly, a level where you played as Anakin against the droid battleship in a Naboo Starfighter was planned for the first game (with a piece of the post-level cinematic shown in trailers) but was scrapped, most likely because Episode 1 already had the podracing level. It was included as a bonus level in ''The Complete Saga'', redesigned to be more like that game's vehicle levels.
** Demos for ''LEGO Marvel Superheroes'' showed that the Green Goblin could turn into his [[WesternAnimation/UltimateSpiderMan Ultimate]] incarnation. They are instead separate characters in the actual game.
*** Also, Lady Deathstrike was originally going to be in the game, but was cut.
** The box art and the mini comic for stage five suggests that Tony was originally meant to upgrade to the Mk. 7. Instead he goes to Mk. 42
