* MissingEpisode: The Avengers vs. The Dark Knight Rises Part 2 was never shown because of the tragic shooting during The Dark Knight Rises premier.
* TheOtherDarrin: Lampshaded by Batman and other characters who demand to know why Rhodey looks different in the second Iron Man film.
** Real-life version: Starting from the Thanksgiving video, Random Guy's sister provided the voice of Batgirl (as it was revealed him and his girlfriend broke up), there is no information on who'll be voicing the female characters in the future.
** The 100th episode song also contains the line "If Marvel and Edward Norton simply can't agree, we'll see Bruce Banner being played by David Duchovny". Of course, the real TheOtherDarrin [[TimeMarchesOn turned out to be Mark Ruffalo]].
* [[TheOtherDarrin The Other Action Figure]]: The Iron Man action figure used in the 2007 videos was replaced with the one licensed to the 2008 movie.
** The convention videos use alternate Spider-Man action figures, as the regular movie-based figures aren't allowed due to orders from Marvel. The viewers are always confused.
** This trope was also discussed in several videos.
** And then there's the part in '''After Hours''' when Superman and Batman are arguing with each other, they then switch between that, and [[spoiler: their SuperFriends action figures, where they then proceed to be kind, and sweet and nice to each other.]] It's rather sickening, to be honest.
** The Thing figure in the "Film/FantasticFour Quickie" differs from the one that made token appearances in later videos.
* ScheduleSlip: ''Zero Hour'' started in 2009. The finale (episode ''7'') finally debuted in 2013.
