Continuity mistake: At the beginning of the fight in the Amazon, Sprite runs to Karun to protect him like Kingo asked. In the wide shot there's nobody on the porch behind him, but when she calls him 'young man' suddenly there are a couple of people there. (01:13:00)
Continuity mistake: During the Bollywood shooting, take a look at what goes on onstage after Karun Patel introduced himself. At the line "You have risen, Mighty one", Kingo is directly behind his co-star and both face the camera, but they were side to side just a moment before. (00:44:20)
Other mistake: In the credits you can read a thank you for some of the filming that took place "at the Manoeuveres and Shooting Range of Paraja." Besides the misspelling of "manoeuvres", the shooting range is in Pajara, in the Canary islands. (02:34:00)
Other mistake: Phastus says "I always wondered how we survived the destruction of other planets that we were on." Always? That's odd phrasing; he learned the mere fact that they have been on other planets that ended up destroyed only literally a few hours before.
Continuity mistake: When Thena stabs the Deviant, he grabs her spear for a moment, then before the cut pulls the arm back. Next shot and he repeats the movement. (02:04:45)
Other mistake: During the fight against Ikaris on the mothership, Thena is not wearing the bracelet that allows the formation of the Unimind and that she wore when she was suited up. (01:55:45)
Other mistake: Makkari looks for the Emergence using Phastos' special radar that he built. She comes back to base telling them she found the Emergence point, but does not say where it is. Despite leaving early, Ikaris is already there waiting for them; he doesn't have any problem finding it himself.
Audio problem: When Sersi helps Phastus on his feet after the Unimind's plans exploded, she yells "He lied to us", but her lips are not moving. (01:46:40)
Continuity mistake: When Ajak lands on the fresh snow after she was pushed down, the camera is behind Salma Hayek, and we see her move her hand tap the snow a few times leaving some prints. Reverse angle, and there are fingerprints in the snow around the position her hand is in, showing it moved. (01:40:05)
Continuity mistake: When for some reason the two Eternals in Phastos' living room feel they have to hide the fact that they're looking at his family life, they sit down in a rush and Ikaris reads some product placement. The objects on the table change position between shots - for instance, look at the Connect Four board. (01:26:55)
Continuity mistake: Phastos' son screams excited that Ikaris is Superman; Phastos calms him down with his hand, but his son touches him in return on the inside of the elbow. Next shot and Jack's hand is in a different spot. (01:26:20)
Continuity mistake: Sersi is staring at the monstrous tree she shaped the Deviant into. Camera to her right; her wet hair is all behind her back. Close-up; hair cascades in front of her right shoulder. (01:19:10)
Continuity mistake: When Sersi is talking with Dane in the middle of the jungle, you can tell by the position of her fingertips in the reverse shot that she is holding the phone in a different way than the opening view. (01:10:45)
Continuity mistake: When everyone looks at Thena for biting the food off her fork with psycho stares at the guests, Kingo's hand goes on/off the mug several times. Particularly obvious when Gil obnoxiously says "I gave you the same thing, Sprite." (00:53:20)
Continuity mistake: Angelina Jolie's stance and the position of her hair change between shots when Sprite dissolves the illusion dome that brought her back to normal. (00:52:50)
Continuity mistake: When Phastos cures Thena's hysteric outburst by punching her lights out, he gets down on one knee to check on her. Which knee, that depends on the shot; right first, then left. (00:38:20)
Continuity mistake: When Thena faces Phastos in Tenochtitlan, their exchange of blows ends with her striking a cool pose with her sword upside down. Angelina Jolie's hands are in two different positions in the two shots, though. (00:38:00)
Audio problem: Ikaris says by mistake "I am very beautiful" in the local language. Sersi laughs and he asks what did he say. She says "You said..." but Gemma Chan's face is not moving. (00:29:10)
Continuity mistake: When Makkari peeks at the Babylonians having a scuffle, most people at the table are seated, but in the next shot it's a full fledged brawl with everyone at the tables participating. (00:26:35)
Continuity mistake: Gilgamesh opens the door and walks towards the oven outside. During the scene, the shadows by the oven change depending on the shot. (00:50:35)
