With the Justice League movie confirmed to be on it's way in 2018, the question that is on everyone's minds is "Who will be in the [Justice League](movie:401267)?"
When it comes to size of the main Justice League roster, a team of 7 or 8 is the most common. With Batman, Superman and Wonder Woman confirmed for Justice League, and Cyborg all but confirmed due to his involvement in the upcoming Man of Steel sequel [Batman v. Superman: Dawn of Justice](movie:711870), this leaves us with 4 other openings.
Green Lantern and Flash have always been main members of the Justice League, so I would bet my house that they will be included. I could also see them Including Martian Manhunter into the main roster.
That leaves us with one more opening. An opening that I could see a lot of people be happy with Green Arrow filling.
Green Arrow has been coming on to our screens for the past 2 years on the hit CW Show 'Arrow', and I know many fans would be delighted to see him included in the Justice League movie.
Stephen Amell, the actor who portrays Oliver Queen/ The Arrow, revealed in an interview with Fandango that he has had discussions about an upcoming Justice League movie
I HAVE HAD DISCUSSIONS, BUT I THINK THE GESTATION PROCESS FOR THIS PROJECT IS A LOT SLOWER THAN MOST PEOPLE THINK. I MEAN, THEY HAVEN’T EVEN SHOT THE NEXT ONE.
The inclusion of Green Arrow into the Justice League movie could open up a range of possibilities. The inclusion of Deathstroke as a major villian in Arrow could set him up as a villain for future Justice League movies. Amanda Waller and the Suicide Squad could create an interesting storyline, and the League of Assassins could create a potential threat for the Leaguers.
