Warner Bros/DC confirm Aquaman film

A while back we received rumors that Jason Momoa was in negotiations to play Aquaman in the upcoming Warner Bros/DC Comic movie, Batman v Superman: Dawn of Justice, and a separate Aquaman film. There are now reports that Warner Bros. has commissioned not only one, but two Aquaman screenplays and that Momoa's casting is basically confirmed.

Last week we got a schedule of release dates from Warner Bros. through the year 2020 and speculation immediately began on exactly what all of those release dates might be. The plan is obviously to compete with Marvel's Cinematic Universe and create a similar one for the new DC Universe that was kicked off by Man of Steel last year.
So far we have Gal Gadot portraying Wonder Woman in Batman v Superman and it's being assumed that one of the many untitled projects is a solo Wonder Woman film. The focus now has shifted to Aquaman where Warner Bros. is "aggressively" developing the project as they have commissioned two screenplays in hopes that they could use one or combine the two for a quick development process. Script #1 is being written by Gangster Squad writer, Will Beall, while the second script was given to 300: Rise of an Empire writer, Kurt Johnstad.
As far as Jason Momoa goes, there hasn't been any official release by Warner Bros. regarding his casting, but it's pretty much a given that if he is playing Aquaman in Batman v Superman that he will also helm the solo movie and be part of Justice League. Recently a Detroit radio station was caught red-handed teasing the project and Momoa's involvement, but director Zack Snyder made a surprise call into the show and claimed that Aquaman could, "cut the flesh of Superman if they came in contact." If that's the portrayal they're going for then I guess they picked the right actor.

There are so many untitled dates on the Warner Bros/DC schedule so it's difficult to wrap your head around it all, but realistically speaking we could see Aquaman as early as 2016. There is a spot on August 5, 2016 as well as two unfilled dates in 2017 (June 23rd and November 17th). There is no real timetable on Justice League anymore, but many expect it by 2017. Realistically at this point we could have solo films for Wonder Woman and Aquaman in 2016 and early 2017 and have Justice League on November 17th.
However, Zack Snyder is currently shooting Justice League back-to-back with Batman v Superman, so they might turn tradition upside down and release Justice League in 2016 before any other solo films. There really is no telling, but I don't know why they would let a project sit on the shelf for two years after filming wraps.
