It is the latest blockbuster role for Morrison, who has carved a niche for himself in big budget movies.
It won't even be the first time he has played father to classic characters. He is best known for his role as Jango Fett in the Star Wars prequel trilogy, where he played Boba Fett's father.
The former Shortland Street actor recently voiced Moana's father in the hit Disney animation.
Morrison previously took on superhero duties for the DC universe when he played Abin Sur in Green Lantern, which was directed by Kiwi Martin Campbell and co-starred Taika Waititi.

Aquaman tells the story of Arthur Curry, the King of Atlantis who can control ocean-based animals and breathe under water.
Widely seen as a joke character, Curry has been reinvented in recent years to become more serious and deal with political issues.
Momoa first appeared in the role in Batman v Superman, and will next be seen in Justice League, Part One later this year before his solo outing.
Other cast members include Amber Heard as Curry's wife, Mera, Willem Dafoe, Patrick Wilson and The Get Down star Yahya Abdul-Mateen II as villain The Black Manta.
Aquaman starts filming in Australia in April, and will be released November 2018.
