!! The 2007 Film:
* HilariousInHindsight: [[https://www.youtube.com/watch?v=1tGXEATdxIc A billboard]] found in the background of a scene promised that a ''ComicBook/{{Batman}}'' and ''ComicBook/{{Superman}}'' crossover movie was in production JustBeforeTheEnd. 6 years after the release of the movie, [[Film/BatmanVSupermanDawnOfJustice it was officially announced]]. Even more amusing is that [[Film/SuicideSquad2016 Will Smith was signed on to appear in another movie set in the same shared universe as that film]].
* MemeticMutation: GODDAMNIT, [[BeamMeUpScotty FRANK]] and WOLL SMOTH, which spun into an entirely unrelated meme.
* OneSceneWonder: She has about 1 minute and a half of screen time at the beginning of the film (and isn't listed in the credits), but Creator/EmmaThompson as Alice Krippin is so delightful you desperately want to know more about the woman who inadvertently created TheVirus.
* SpecialEffectsFailure[=/=]UncannyValley: The zombie/vamps are pretty obvious CG. They tried using extras at first, but since it required constant hyperventilation, they were forced to use CG instead.
* TheyWastedAPerfectlyGoodPlot: The film's alternate ending comes closer to the message of the novel than the ending that made it into the movie and fills the above-mentioned plot hole, in addition to many others. It did poorly with test audiences, though, so ExecutiveMeddling changed it to an ending that is completely different and misses the point of the entire novel, twisting the message so that it can still fit the title, but in almost the exact opposite way that the original ending fit it.
* TheUntwist: At least in the cinematic version.
