The Justice League (DC's version of Marvel's Avengers) movie will not, speculating from what Henry Cavill said in a recent interview, be in cinemas in the near future.  

Should such a film be made would we see Cavill as Superman saving the world (or possibly the universe) alongside Christian Bale's Batman and Ryan Reynolds's Green Lantern?  They would, of course, be supported by a team of other less known superheroes: Wonder Woman, Martian Man-hunter, Flash and Aquaman.

Rumours are currently circulating that DC Comics could be developing projects for Wonder Woman, Flash and Aquaman. As most of us mere mortals no little about the origins of Wonder Woman or Aquaman - and who has ever heard of Flash?- developing these characters seems to be of more importance than a Justice League Film. 

Considering Marvel's Avengers had films made about most of their key characters: Iron Man, The Hulk, Captain America and Thor before they were ever united, it does seem premature that Superman will pair up with his own group of superheroes. We haven't even been formally introduced!

Christian Bale
Should a Justice League movie be made would Christian Bale come back as Batman?

Cavill seems to agree as he said in his ABC interview that a Justice League movie could only be done once the appropriate situation was set up as "It may take some time of building up other movies and other characters and introducing them together in one way or another"

In the same interview he points out that the characters in Marvel differ slightly to those in DC as the characters, including Superman, are "all god-like in their power" continuing on to point out that by it's difficult to incorporate such power in "this real-world universe, real-world setting we're telling our story in".

Ryan Reynolds
Or will Ryan Reynolds return as The Green Lantern?
