Justice League ramped up its promotion this past weekend with a new trailer that tried to change the tone of the DCEU to a more positive, heroic stance. After the team goes "All In" with their battle against Steppenwolf, the shift of Warner Bros. and the execs at DC will be to develop the standalone solo movie centered around Jason Momoa's Aquaman... and it looks like the James Wan production still has a few key secrets waiting up its sleeve.
Graham McTavish is a Scottish film and television actor whose vast screen credits include Outlander, Preacher, Creed, the Hobbit trilogy, and the 24 serial. His addition to James Wan's Aquaman cast feels like a late add, but it's more than probable that he has been part of the ensemble this whole time, but kept under wraps -- of sorts -- because his mysterious role is too important to reveal at this stage.
Up until this point, the Aquaman cast is looking beyond stellar, with leading hero Jason Momoa being joined on screen by Amber Heard (Mera), Nicole Kidman (Queen Atlanna), Willem Dafoe (Vulko), Dolph Lundgren (King Nereus), Yahya Abdul-Mateen II (Black Manta), Patrick Wilson (Ocean Master) and Temuera Morrison (Thomas Curry). The movie, which filmed in Australia, will show off all corners of Atlantis, the undersea kingdom ruled over by the Atlanteans. I also wonder how much of that world we will witness in Justice League, as there have been scenes of battle footage in the most recent JL trailer, suggesting plenty of Aquaman action.
The future of the DCEU remains a mystery, to a certain extent. While it appears that Justice League is about to introduce several important heroes such as The Flash (Ezra Miller) and Cyborg (Ray Fisher) into the established fold, we have been told that upcoming movies might not be contributing to an interwoven tapestry the way that the MCU films often do. So whomever Graham McTavish is playing in Aquaman might not be that important to the DCEU as a whole, though the "secret" role seems important to Aquaman.
