Justice League (TV Series) - Casting and Character Changes

Casting and Character Changes

Kevin Conroy reprised his voice role as Batman from Batman: The Animated Series (1992–1995), The New Batman Adventures (1997–1999), and Batman Beyond (1999–2001). Conroy pitched his voice to a range in between the voices he'd used in the previous shows; it was deeper than the voices he used in the first two series, but still higher-pitched than the voice he used in Batman Beyond. In addition, Batman's uniform was also redesigned, given a mixture of his previous animated costumes. It was basically the same Batsuit from The New Batman Adventures, but had the blue highlights from the original series' costume as well as longer ears from Batman Beyond on his cowl, and his body now is thinner instead of bulkier, unlike his appearance from The New Batman Adventures.

Tim Daly, who voiced Superman in Superman: The Animated Series (1996–2000), did some early recordings, but was ultimately unable to reprise his role due to his involvement with The Fugitive (a short-lived remake of the original 1963 TV series), and was replaced by George Newbern. Superman was initially redesigned to have a bit of a squint to his eyes and slight wrinkles that was also meant to make him look older, in addition to having a noticeable shining streak to his hair; he was redesigned to appear larger in physical girth than in the previous series. Fans did not like the older appearance and in the second season the streak was toned down to the point of almost disappearing and the squint was removed, in essence reverting Superman to his earlier animated look. As an in-joke, Superman's season one facial designs are used for an older Jor-El in the Justice League Unlimited episode For the Man Who Has Everything.

Most of the characters retained their general comic book origins and continuity, with Wonder Woman being the notable exception. In the Justice League series continuity, the premiere story arc "Secret Origins" revises the plot of Diana's competition against her fellow Amazons to be the ambassador of peace to man's world, and she is referred to as a "rookie" superhero during her first encounter with the League. (Subsequent episodes touched on her attempts to adjust to her new world). In an interview segment on the Season One DVD, Bruce Timm stated that he initially ran into some legal issues in using the Wonder Woman character, but was adamant that she be used in the series. Additionally, the character of The Flash was portrayed as somewhat younger and significantly more brash than his comic book counterpart, taking on a number of personality traits of Plastic Man, who provides a similar comic relief function in the JLA comics. Major changes were also made to the Hawkgirl character. The character of Hawkgirl became romantically involved with the John Stewart Green Lantern as the series progressed. A romantic relationship between Batman and Wonder Woman was also "showed" (hinted at but never "official" unlike Hawkgirl/Green Lantern) by the show's creators, who disliked pairing Wonder Woman with Superman.

In the comic books, the Martian Manhunter / J'onn J'onzz has a power called "Martian Vision" which has been shown both as a beam of pure force (an extension of the telekinesis that allows him to fly), and essentially the same as Superman's heat vision. Neither power was ever shown in the series, except in the ending of the episode "The Savage Time", dropped presumably in favor of his phasing power, shapeshifting and telepathy. Despite this, Martian Manhunter has this ability in the "Justice League: Chronicles" video game based on the show. The Martian Manhunter was only referred to by that name in one episode and otherwise called simply J'onn.

Although the series itself is animated in traditional 2-dimensional style, the opening credits are rendered in 3D with toon shading. The intro is a "stock" intro used throughout the series until Justice League Unlimited premieres.
