This was the standard of a Batman and Superman movie for almost 20 years.
I remember watching this as a little kid and I enjoyed it a lot, and all these years later it is still good. Released almost 20 years before the Batman fought the Man Of Tomorrow , this movie takes a different approach to the team up, although it does share some similar factors with the new movie. Batman and Superman have been doing their own things in Metropolis and Gotham, until one day both The Joker and Lex Luthor team up to kill both Batman and Superman. This causes the Dark Knight and the Man Of Steel to team up and stop their plans from, you guessed it taking over the world. The single most best element of this movie is that it takes place in the Animated Series universe or the Diniverse as fans call it, the universe where both Batman The Animated Series and Superman The Animated Series are found. If you were a fan of either of these shows, then you pretty much know the mythos and the voice acting and the animation style. All the original cast of both shows are here, and really that's half the fun of this movie. How would Superman and Batman talk to one another? Would they fight or work together? What would Joker and Lex be working towards and all the stuff that would happen between them? And in this universe, they do it pretty well. You can believe like, this is what would happen if these two met. And that's where the cast shines in this movie. They get to do something that is not what they do on a regular basis. Kevin Conroy and Tim Daly show that despite their different stances, Batman and Superman could work together costumes or not. Mark Hamill is glorious as always and it's just so funny to see him paired up with Clancy Brown's very serious Lex Luthor, you just don't see that anywhere else. If you want a good prelude to the new Batman V. Superman movie this would be a good place to start. And the film's running time is, and I kid you not...one hour. Just one hour. And they do a spectacular job with everything they put into such a short movie. Unfortunately I couldn't really find it anywhere besides in stores but the DVD is only $5 so it's not a waste of money. Whichever Batman and Superman movie you see first, I hope you enjoy both.
