There was Aquaman news yesterday, it just wasn't the official confirmation of Jason Momoa. According to THR, Warner Brothers has not one, but two writers working on an Aquaman script separately. Both writers are from Warners' "stable of scribes". Will Beall who wrote Gangster Squad for the studio and Kurt Johnstad who worked on the 300 movies with Zack Snyder.
Dual tracking a movie, hiring two separate writers for the same project in hopes of getting the best product, also tends to produce results faster… and with nine untitled movie dates announced recently, that may be just what Warners needs. The next unnamed movie date is August 5th, 2016 with two more in 2017.
Aquaman was not on Nikki Finke's list of upcoming Warner/DC movies.
