Incredible underwater scenes and a new hero: Decoding Aquaman's new-trailer

The trailer firstly shows bits of Aquaman's origin, how he was born of both land and Atlantis.

Also starring Amber Heard, the trailer then goes on to show their quest for Neptune's Trident and a battle for Atlantis.

For those unaware, the Trident is an incredibly powerful weapon in comic lore. It is Aquaman's symbol of power, the weapon of choice, and unites Atlantis.

Every superhero movie needs a villain. In Aquaman's quest to get the trident, he has to face the present king of Atlantis, Orm.

However, the best part of the extended trailer was the introduction of Black Manta.

Manta, in comics, is an armored assassin and one of Aquaman's recurring villains.

In the film, Yahya Abdul-Mateen II plays the role of Black Manta.

The trailer promises a classic Aquaman story, where Atlantis wages war against all land dwellers.

To stop this quest of global domination, Arthur Curry, played by Momoa, must step up to fulfil his destiny as the rightful heir of Atlantis.

A classic shot shows Momoa's Curry dressed in traditional Aquaman's uniform and holding the trident, signaling the arrival of a new hero.

DC is infamous for dark and serious movies which have not found traction with audiences.

However, under James Wan's direction, this film takes a lighter approach. Mera, played by Amber Heard, and Curry share moments of banter to prove it.

Wan, who directed 'Furious 7' has also included excellent action sequences.

'Aquaman' might finally be a step in the right direction for DC movies.
