Batman:The Animated Series Wiki

This is general information about production inconsistences, mistakes and external references related to the episode Heart of Ice from season one of Batman: The Animated Series.

  • The plot of this episode was largely used for Freeze's revised origin in the 1997 graphic novel Batman: Mr. Freeze, also written by Dini.
  • In February 2002, to celebrate the tenth anniversary of Batman: The Animated Series, polls were held at the website The World's Finest to determine the best episode of the show. "Heart of Ice" was the winner and so received its own sub-site, complete with exclusive comments on the episode provided by Bruce Timm, Paul Dini and other officials behind the show.
  • In 2005, Wizard Magazine selected this episode as the best of the series.
  • This episode provided such a burst in the popularity of Mr. Freeze that his comics' counterpart has his origins retconned to more closely resemble this episode.
  • The episode inspired a story-based campaign for Batman: Arkham Origins, titled "Cold, Cold Heart". Set a week after the events of the main game, on New Years Eve, the narrative focuses on the origin of Mr. Freeze, who attacks when Ferris Boyle is presented with a "Humanitarian of the Year" award.
  • This episode contains two references to the film Star Wars: The Empire Strikes Back:
  • Batman trapped upside down in a cold cave is similar to what happened to Luke Skywalker early in the movie;
  • Batman returns a criminal partially frozen by Mr. Freeze to health using a similar device to the "bacta tank" that revives Luke. Interestingly, Luke Skywalker was played by Mark Hamill.


  • Twice in this episode Batman's chest logo colors are reversed. In the commentary, Paul Dini and Bruce Timm said this was deliberate, a subtle nod to past cartoons with their usual animation errors.
  • The security footage of Fries' confrontation with Boyle and subsequent accident is taken from several different angles, including a close-up of Boyle's angry face, yet there are no security cameras anywhere near the required positions. This is also noted by the creators in the DVD commentary.
