It was first rumored back in mid-June that Game of Thrones star Jason Momoa would be making an appearance as the superhero in Zack Snyder's upcoming Batman v Superman: Dawn of Justice, but that's not all the studios have planned. Apparently there is a solo movie in the works as well, and today two writers have been hired to work on scripts.
This news comes to us from The Hollywood Reporter, which says that both Will Beall and Kurt Johnstad have been hired to start working on Aquaman - but they won't be working together. Instead, each of them will be working on their own screenplay, and which ever one is deemed best will be adapted as a part of DC's growing Cinematic Universe. The assumption is that the aquatic superhero movie will be one of the nine untitled projects that have been announced to be released between now and 2020, but obviously we don't know where it will fit in at this point. The three earliest dates following Batman v Superman: Dawn of Justice's release in March 2016 are August 5, 2016, June 23, 2017, and November 17, 2017.
