It looks like Warner Bros.' upcoming Aquaman movie is going to be a complicated family affair. It has been announced that Aquaman's evil half-brother Orm, aka Ocean Master, will be appearing in the first solo outing for the Justice League's resident Atlantean warrior. What's more is that Fargo and The Conjuring star Patrick Wilson has been cast to play the part in the movie.

The news that Patrick Wilson will be joining the growing cast of Aquaman as Orm comes courtesy of Deadline. For those who may not be familiar with the character of Orm, he is a relatively new character in the DC Comics canon, first appearing in the 2012 run of Aquaman as part of the New 52 initiative. Ocean Master, however, has been around for quite some time, but his origin was retconned in 2012 to make it so he was the second son of Queen Atlanna and a descendant of Orin. He is extremely powerful and is a rival for the throne of Atlantis in the comics, so there could be some serious drama going on between him and his more famous brother in the movie. This could bare similarities to what Marvel did with Loki and Thor in the Marvel Cinematic Universe, because it certainly does in the comics. So Warner Bros. could be taking a cue or two from Marvel Studios on this one.

As for Patrick Wilson, he will be joining Jason Momoa, who is playing the title character of Aquaman, aka Arthur Curry in the movie, who will first be appearing in Justice League in November of next year (not including his brief email cameo in Batman V. Superman: Dawn of Justice). The cast of Aquaman also currently includes Amber Heard as fellow Atlantean Mera, as well as Willem Dafoe, who is playing Nuidis Vulko, both of which have roles in Justice League as well. Patrick Wilson has a good relationship with Warner Bros. and has starred in a comic book movie for them previously, playing Nite Owl in Zack Snyder's Watchmen. He also starred in both The Conjuring and The Conjuring 2 for director James Wan, who is directing Aquaman. So his casting actually makes quite a bit of sense.

It is unclear at the moment if Orm will be the primary villain of Aquaman. At the very least, he probably won't be the only bad guy squaring off with Arthur Curry in the movie. We reported a few months ago that long time Aquaman bad guy Black Manta was scheduled to appear in the movie as the main antagonist. Perhaps he and Orm could team up to try and take down Aquaman? Or maybe this first movie will simply build the tension between Aquaman and Orm, setting him up as a potential villain for a future movie. Maybe even Justice League 2? Sort of like how Marvel made Loki the primary villain for The Avengers. There are a lot of possibilities.

Recently, Aquaman had its release date shifted from July 27, 2018, to October 5, 2018, giving James Wan a little more time to get this movie right. Even based on what little we have seen of Aquaman so far, it is very clear that this won't be the laughable version of the character from the old Justice League animated series. The movie has a very promising director and with the addition of Patrick Wilson, an increasingly promising cast. Let's just hope Warner Bros. can get things moving in the right direction elsewhere in the DC Extended Universe so James Wan can do his thing with Aquaman. We will next see Aquaman in Justice League on November 17, 2017, which should plant some seeds for the character's first solo movie. Maybe we'll even get an Orm cameo?
