The solo Aquaman film was originally slated to hit theaters in July of 2018, but that was later shifted later in the year to October. Well, it seems that Warner Bros has moved the date yet again — now delaying the film until December 21, 2018.
Some of the films in the DCEU have been marred with delays and issues, most notably The Flash‘s constant parade of changing directors and The Batman‘s relative instability, but Aquaman seems to be the one post-Justice League film still on track. Most likely this delay is intended to give the film, which is expected to start filming soon, more time to work on special effects and post production.
That December release date originally had Avatar 2 pencilled in, but as that film has been delayed, it leaves the weekend open for the studio. It does mean that the Aquaman film will now share its release date with the (still untitled) animated Spider-Man film which will feature Miles Morales. It’s a gamble for the studio to say the least, but I guess we’ll see how it turns out.
