Patrick Wilson has been cast as supervillain Orm Marius aka Ocean Master in Warner Bros' upcoming superhero outing Aquaman. The Fargo star will appear alongside lead Jason Momoa in the James Wan-directed movie.

In the comics, Ocean Master is actually Aquaman's human half-brother and is one of his greatest enemies. Regarded as somewhat of a antithesis to Arthur Curry's hero, the pair share a relationship similar to that of Thor and Loki in Marvel Comics. Orm is known to be a powerful mischief maker, tired of living in his sibling's shadow and hell-bent on usurping Aquaman and ruling Atlantis himself.

He possesses magical abilities including telepathy and, in more recent issues of the comic, is seen wielding a trident that controls lightning and a helmet that allows him to dominate massive volumes of water. Also in the comics, he struck a deal with demon Neron which, while bestowing him immense power, caused his face to become horribly scarred. However, its unknown whether this will be visible with Wilson's onscreen version.

Given his filmography, it's unsurprising that Wilson is attached to the project. The 43-year-old previously worked with producer Zack Snyder on action fantasy Watchmen in 2009, playing superhero Dan Dreiberg aka Nite Owl. More recently, he's been a somewhat right-hand man for Wan too, starring in the The Conjuring, Insidious and their respective sequels. He also voiced the president of the United States in Batman v Superman: Dawn Of Justice.

Aquaman also stars Amber Heard and Willem Dafoe, and is currently scheduled to reach US cinemas on 5 October 2018. There is no official word as to when it will be released in the UK yet.
