The latest report for the Justice League Iceland shoot lends further credence to the idea, revealing that the scene(s) being filmed there involve multiple Aquaman characters/actors.
The timing of the Iceland shoot for the latter will therefore give Momoa and his future Aquaman solo film costars a chance to work together, before they reunite for production on Wan’s superhero movie.
However, filming on Justice League in general is not yet done; the production has instead shifted to Iceland, with the small village of Djúpavík serving as the primary setting for the sequences that are being assembled there.
