Despite the obvious writings on the wall, Warner Bros. and DC have been quite reliant on not confirming that Jason Momoa is indeed Aquaman. However, it all came to an end when the studios announced its slate of DC films throughout the years until 2020.
Jason Momoa is indeed the right man for the job, though we understand that some fans might have preferred if he was chosen to take on the role as the Main Man, Lobo. However, one should bear in mind that this actor did a splendid job as Kahl Drogo in Game of Thrones, and that is the type of performance we should want to see with Aquaman.
At the moment, DC and Warner Bros. have the perfect time to change how Aquaman is viewed in popular culture. The character is still being shunned due to his portrayal in the Super Friends cartoon series, and despite the many changes decades after, Aquaman is still seen as a wimp who talks to marine life.
