We likely won't see a trailer for Zack Snyder's much-discussed team-up film Justice League until later in the year, or possibly early next year. That hasn't stopped enterprising fans from creating their own versions, and Youtube user Stu Whitten has created one of the best ones so far.
Implementing footage from Man of Steel, Batman v Superman: Dawn of Justice, Wonder Woman, and even Injustice Gods Among Us 2, Whitten perfectly encapsulates the scale of this project and layers in some great action shots of each hero. The Injustice footage comes in about midway, in a brief shot of Flash dashing off into the distance. It makes sense since the speedster's one appearance in Batman v Superman was coming through a boom tube, which wouldn't be easy to edit in.
Hopefully, the team at Warner Bros. will look at fan trailers like this for some inspiration, but once people see Batman, Wonder Woman, Superman, Aquaman, The Flash, and Cyborg sharing the screen together for the first time, it wouldn't be a stretch to predict people losing their minds.
Justice League is filming now, and features the return of Ben Affleck (Batman), Gal Gadot (Wonder Woman), and Henry Cavill (Superman) along with new additions Jason Momoa (Aquaman), Ray Fisher (Cyborg), Ezra Miller (The Flash), and J.K. Simmons (Commissioner Gordon). The film is set to march into theatres on November 17th, 2017.
