Trivia: The Anabelle doll from The Conjuring, another film of director James Wan, is visible while Mera is taking Arthur to her submarine ship. Blurry but there.
Continuity mistake: After the submarine scene, Aquaman shows up on the pier. Check the wooden plank on the right, and you'll see that the puddle changes size three times between instant cuts.
Continuity mistake: Aquaman asks Mera what her name is while a strand of hair runs along his forehead. A shot later, it's gone.
Continuity mistake: In Italy, Mera fights against a guard, who crashes against a bottle cabinet, causing several bottles to fall. A shot later, the bottles are back in place.
Continuity mistake: Mera touches the stone where the Trident of Atlan was created with her left hand. From the opposite immediate angle, her right hand is now extended.
Continuity mistake: When the village is being destroyed, there's a bearded man with a green jacket who runs inside the church to take shelter. A couple of shots later, he is outside the church, running inside again.
Continuity mistake: Mera takes her bracelet off, lays it on the street and smashes it. An instant later, it's in perfect shape. (01:30:37)
Continuity mistake: Mera's hair falls on her arm or not when she lies on the beach shore with the guard next to her.
Continuity mistake: Right when the guards enter the home and the walls explode, Arthur swaps between having short curly hair to it being very long and straight.
Answer: No, Vulko said they had unlocked the secret of unlimited energy whilst the rest of the world still thought the earth was flat. Atlantis was already old by then, so it's definitely older than 2000 years. Atlan ruled over Atlantis for thousands of years. To say Atlantis is over 10000 years old is probably the most accurate.
