Ocean Master will be the main villain in Aquaman coming out December 21, 2018 by Warner Brothers.
Orm is a half-brother of Aquaman (Arthur Curry) who wants to take the throne of Atlantis.
Warner Brothers have released a picture of Orm. I put it side by side with comic version. However, it seems like Orm is holding his mask. In the comic book, he wears the mask pretty much all the time.
Orm will be played by Patrick Wilson. Patrick is famous for his roles in Insidious (2010), Insidious: Chapter 2 (2013), Conjuring (2013) and The Conjuring 2 (2016).
Ocean Master first appeared in Aquaman 29 (September 1966), created by Bob Handy and Nick Hardy. Orm is fully human, unlike his half-brother Aquaman
Back in May Aquaman 29 CGC 4.0 sold for $110.00. Now you are looking to pay $250 for the comic book.
