Most of you know this but for those of you who don't know. The first appearance of the league was in the "Brave and the Bold" issue 28 of 1960. The original roster featured was Superman, Batman, Wonder Woman, Manhunter, Green Lantern, and the Flash. In 2011 DC Comics revamped the DC Universe calling it the New 52. In the relaunch Martian Manhunter is no longer at the core of team. In his spot we now have Cyborg. Over the years the teams main members have changed countless times.
So the question is who will Warner Brothers Studio use as the team's core members. Or the equally important question who do you the comic book fans want to see in the Justice League movie?
I think Cyborg is a great character with a lot of star power. I'd love to see him in a Titans movie or even the lead in his own film. But personally Im hoping for the cookie loving Martian. It would be awesome to see the original seven on the big screen.
