The "Justice League" movie will have the pressure to beat the most profitable superhero movie "Avengers Assemble" which made more than $ 1.5 Billion. However, unlike Marvel, Warner Bros. has the full roster of DC characters at their disposal.

But is that advantage enough? It depends on how the studio uses them. Marvel, for example needs to reinvent some of their storylines like Civil War, as heroes like Spider Man and Wolverine play a significant role in the plot. Warner Bros. will not have that problem.

Who will be included in the official roster?

So far the confirmed members, along with the actors who'll play them are: Superman (Henry Cavill), Batman (Ben Affleck), Wonder Woman (Gal Gadot), Cyborg (Ray Fisher). Aquaman is heavily rumored to be played by Jason Momoa but this information has yet to be confirmed. Casting for The Flash and Green Lantern is also not confirmed but they are also part of the League.

One very popular character that fans clamor to see is the Martian Manhunter. As Movie Pilot suggests, an actor who can project the enigma of J'onn Jonzz/John Jones is Benedict Cumberbatch. The proposal:

"Cumberbatch can play an amazing detective, as seen by his Emmy award-winning performance as Sherlock Holmes. He also has to feel a bit alien in nature, which he also embodies as Sherlock with his otherworldly presence and intellect. To top it all off, he has one of the most intriguing voices in the industry. This is a superb actor who can be believable as a Martian, but also bend in as a human."

It's highly unlikely that they take an actor with Cumberbatch's caliber (and price tag) but if "Batman V Superman: Dawn of Justice" underwhelms (or falls short of "Avengers Assemble")  then they could take their cue from Tom Hiddleston's popularity as Loki.

"Justice League" does not have an official release date as yet, but there's a strong indication that Warner Bros. targets a 2017 release date.
