Jason Momoa's Aquaman is one of the more anticipated aspects of the upcoming Justice League: Part 1, but now thanks to him fans might have another big reveal to look forward to.

In a recent Instagram post, the actor showed off his physique during a workout session and captioned the video with the line "getting ready for the castle. Watchtower." It looks like the League will get an official home base in the upcoming film.

The Justice League has had two primary Headquarters over the years. The first was the Hall of Justice, made popular in the Super Friends cartoon series. The second was the more recent Watchtower, which was introduced in Grant Morrison's run on the League. Since its introduction, the team has toggled between both, and in some cases used them simultaneously, such as in Brad Meltzer's JLA run.
