Trivia: Futurama's "Anthology of Interest II" episode contained a segment called "Raiders of the Lost Arcade" where Fry asks what would happen if life was more like a video game. In the segment, video games come to life and attack Earth, and it's up to Fry to save the day because of his video game playing skills. Billy West, who voices Fry, later performed voices in "Pixels", which was based on this premise.
Trivia: The version of Batman in the universe of this movie is called Kirk Langstrom. In the original DC universe, Kirk Langstrom is actually the alter ego of one of Batman's villains, known as the Man-Bat.
