When the Joker elicits the help of Lex Luthor in a new fiendish scheme, only the combined superpowers of Batman and Superman can save Metropolis. Will the Man of Steel and the Caped Crusader be able to foil the plot of this diabolical duo? Not if the superheroes' alter egos clash as they vie for the attention of the self-reliant Lois. Watch the action explode as Batman and Superman clash with each other and their notorious archenemies. This feature-length tape began as a three-episode story line on the animated TV series, a superhero crossover where Bruce Wayne visits Metropolis and the Dark Knight meets the Man of Steel for the first time. The two heroes mix like oil and water, the law-and-order Superman suspicious of Batman's rather ruthless methods; but they form an uneasy partnership when Lex Luthor and the Joker team up to take on the duo. To add a personal dimension to the already edgy rivalry, Wayne romances Lois Lane under Clark Kent's very nose. The stylized animation and sharp design of the TV series give the limited animation a sleek, smooth quality and an energetic sense of movement. Timothy Daly supplies the voices for Clark Kent and (in a deeper register) Superman, with Kevin Conroy performing the same vocal trick for Bruce Wayne/Batman; but Dana Delany only has to worry about one persona as Lois Lane. The once-and-future Luke Skywalker, cult film star turned voice actor Mark Hamill, provides the Joker's cackling banter. --Sean Axmaker.
