The hotly-anticipated film - which stars Jason Momoa as the titular character - will now be released on December 21, 2018, rather than its previous October release date.

It will now go head to head with Sony's animated Spider-Man movie, taking the place of 'Avatar 2', which director James Cameron recently revealed wouldn't be able to meet the planned deadline.

And despite having to wait a couple of extra months to see Momoa as the fictional superhero, director James Wan tried to soften the blow when he took to social media following the news.

He simply wrote: "Merry Christmas".

Meanwhile, leading man Momoa previously teased he's "never seen anything like" 'Aquaman'.

He 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 previously made an appearance as Aquaman in 'Batman v Superman: Dawn of Justice' and will do so again in the upcoming ensemble movie 'Justice League' - admitted the movie was "the best moment" of his career.

He shared: "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."

'Aquaman' - which also stars Amber Heard, Willem Dafoe and Nicole Kidman - is now slated for release on December 21, 2018.
