Cosmic Book News recently posted some Batman 2016 movie reboot news about the Joker appearing and more, and now our source has just received some news about the upcoming Justice League movie.

Currently there is a Justice League movie script by Will Beall, writer of Gangster Squad, but no director is attached as of yet.

While that is being decided, fans have been wondering which of their favorite DC Comics super heroes will be chosen for the line-up as part of the Justice League movie in 2015.

We're told that the Justice League movie may feature the original seven founding members: Superman, Batman, Wonder Woman, The Flash, Green Lantern, Aquaman — and Martian Manhunter.

We're further told that the Justice League movie may also feature cameo appearances by Green Arrow, Cyborg, and other "second tier characters."

In addition, we're told Warner Bros. already has actors in mind for the roles, but things could change once a director is attached.

Our source did tell us previously that Henry Cavill is to star as Superman in the Justice League movie.

With the recent relaunch of the DC Comics "New 52" Justice League, it was questioned which team of Justice Leaguers we would see in the new movie. The character of Cyborg was brought onboard the new Justice League comic book last year, with Martian Manhunter becoming a former member of the Justice League (starring in Stormwatch). However, it has since been announced that the Martian Manhunter will be a part of the new Justice League of America comic book set to launch next year by Geoff Johns and David Finch, featuring second tier characters including Green Arrow, Catwoman, the new Green Lantern, Stargirl, Vibe and Hawkman.

Chatting back and forth with our source I did question if the new CW Green Arrow and Wonder Woman television shows, Arrow and Amazon, would have anything to do with the DC movie shared universe, to which the source said the movies and TV will be separate, unlike Joss Whedon's The Avengers and new ABC S.H.I.E.L.D series.

For more on the Justice League movie head on over to everything we have been told from back in June.
