The 37-year-old actor is set to star as the titular superhero in the upcoming DC Comics standalone movie, and has said the script offers a "really cool spin" on the popular comic book character.

Speaking to DigitalTrends.com, Jason said: "I read the ('Aquaman') script and let me just put it this way, I've never seen a movie that's anything like this. It's going to be a world that you've never seen before, which is really cool.

"We went to space, we travelled all over different worlds, but we never went underwater. So it's just a really cool spin on what's below and it uses a lot of great movies that I already love -- whether that be 'Raiders of the Lost Ark' to 'Star Wars' to 'Lord of the Rings' to 'Romancing the Stone'.

"It has a lot of really cool adventure, it's funny and heroic, and there's a lot of different characters and a lot of different worlds that we get to go to. So I've never really seen anything like it."

And Jason - who will first don his swashbuckling superhero costume for the upcoming ensemble movie 'Justice League' - previously said the movie was "the best moment" of his career.

He said: "I haven't been an actor who's been able to pick and choose roles, and being a family man, it's been about putting food on the table ... This has been the best moment of my career because the superhero roles are letting me get the other roles I want."

Meanwhile, it was recently reported that Nicole Kidman was in talks to join the cast as Aquaman's mother Atlanna.

If Nicole does sign up for the DC Extended Universe film - on which shooting is due to start in April - she will join a star-studded cast which already includes Jason, alongside Amber Heard as Queen of Atlantis Mera, Patrick Wilson as the titular character's evil half-brother the Ocean Master Orm Marius, Willem Dafoe as a friend and adviser to Aquaman named Vulko and John Cleese in an unknown role but one that has been described as a "significant part".

'Aquaman' will be released by Warner Bros. Pictures on October 5, 2018.
