Henry Cavill spoke about the possibility of a Justice League movie during a recent interview with ABC News.
Cavill told ABC News:
Justice League could be great if done correctly. It’s a very tough one to do because the DC comic heroes are all god-like in their power. So in this real world universe, real-world setting we’re telling our story in, it’s going to be tough to achieve that. It has to be done very delicately with a lot of thought. So, it won’t be right away. I hope it’s not, anyway. It may take some time of building up other movies and other characters and introducing them together in one way or another.
This is the difference between the Marvel universe and the DC universe. Outside of Batman and Green Arrow, a large majority of the DC superheroes are not nearly as grounded on Earth as the Marvel characters. Of the main characters in The Avengers, Thor is the only none that is not of the planet.
This is a problem with DC. Look at Green Lantern and how well that did at the box office. Having 26% positive reviews at Rotten Tomatoes is not exactly all that flattering either.
For a Justice League movie to really work, it is as if producers would have to hire a screenwriter that knows the mythology of the characters but that’s not the only problem. How does one bring in the Watchtower? It’s either a space station on the moon or orbiting the planet.
Comic book aficionados want to see the film but also want to see it done the right way. Is Christopher Nolan the right producer for such a film? Maybe but I don’t know for sure.
