Jason Momoa's Aquaman begins filming: James Wan shares first submarine image from set

The DC Extended Universe is set to explore the underwater kingdom as cameras have officially started rolling for Aquaman. Director James Wan shared the first on-set image of the highly- anticipated film while weighing on the exhaustive pre-production tasks.

"Months of intensive prep have led to this. Here we go," he captioned an image of what looks like a submarine. The Twitter image also featured a clapper that marks day one, scene one on it with the film's tentative title reading Ahab.

The film is expected to feature a majority of underwater scenes since its narrative revolves around the King of Atlantis, played by Game of Thrones star Jason Momoa. The actor has already shown his mettle in a short tease in Batman V Superman: Dawn of Justice, where Wonder Woman finds him in one of the file videos of metahumans.

The DC superhero film will majorly be shot in Australia. Momoa and his co-star Amber Heard have reportedly been practising for the action sequences.

The first day of production started with principle photography and The Game of Throne star will start filming from Thursday (4 May).

Heard, who will play Mera in the film, has shared a sneak peek of her dedicated preparation for her major role.

Previously, the 37-year-old Momoa talked about a 'heroic' underwater world. "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 traveled all over different worlds, but we never went underwater," he told Digital Trends.

Aquaman solo film by DC will hit theatres on 5 October 2018.
