So it looks like this... Zack Snyder's "Batman v. Superman: Dawn of Justice" (with Henry Cavill reprising his role as Superman and Ben Affleck as Batman) for May 2016 (which we already knew), followed by a "Shazam" movie in July, 2016, and Joseph Gordon-Levitt's adaptation of Neil Gaiman's "Sandman" set for that Christmas. We don't know anything about "Shazam," although at various times "Wedding Crashers" director David Dobkin was attached and The Rock was rumored for the title role, a superhero that is birthed every time a wimpy news reporter says the word "Shazam."
After that, it's a "Justice League" movie in May 2017, which, again we had heard about already, and will reunite much of the cast of "Batman v. Superman: Dawn of Justice," and director Zack Snyder. In July 2017 it's a "Wonder Woman" solo film, presumably starring Gal Gadot as the Amazonian princess. Then, in the Christmas of 2017, there will be a Flash/Green Lantern team-up movie, although this sounds super bizarre, and not just because "The Flash" will soon launch as a CW live-action series (with Grant Gustin as Barry Allen) but also because Ryan Reynolds just tried to anchor a "Green Lantern" movie and the results were negligible (at best). If this movie happens, Finke assures us that it won't be Reynolds in the mo-cap green suit. Finally, "Man of Steel 2" is tapped for May 2018, which means the studio is backtracking on their stance that "Batman v. Superman" is actually a "Man of Steel" sequel. Instead, it seems to be an in-between-er that links "Man of Steel" and the "Justice League" universes.
Finke also let slip the reason behind the "Batman v. Superman: Dawn of Justice" delay, from the bloody summer thunderdome of 2015 to the somewhat less crowded summer 2016 arena: according to her source, "Like 'Marvel's The Avengers,' there will be cameos of superheroes for future installments. The cameos will include the already known Cyborg and Flash. Green Lantern [not played by Ryan Reynolds, thank god] may be introduced. And Aquaman will be seen in the Justice League movie. Problem is, Warner Bros Pictures was still negotiating with the actors for those cameos and future roles, meaning major contracts for multiple JL/character films to follow. The studio didn't want to move forward until they had more of this secure so they held off starting production for a few months. Seemingly simple reason, but the implications are pretty darn huge."
So there you have it. Will Warner Bros and DC finally be giving the folks at Disney and Marvel a run for their money?
