Continuity mistake: Ari during the break from the party begins her seductive scheme; posing as a waitress at this guy's own engagement party, she approaches him while he is -for some reason - in the parking lot, makes him smoke a joint for the first time in front of his car, and kisses him - apparently all of this is super easy, barely an inconvenience. When she touches his face, she lowers her fingers from the chin at least 3 times in separate shots when she is whispering things to him. (00:11:50)

Continuity mistake: When in the first pub and it turns out one guy is tee-total and will only drink water, there is a shot of the glass from the inside as the pint of water is drunk down to the bottom. In the next shot, from the side of the table, the glass has some in - around 1/3 full.

Continuity mistake: As El Camaleon pulls the Cuba Gooding Jr. face off, there's an unshaven neck with a tattoo visible under it. After the cut, Lady Gaga's face (also presumably unshaven admittedly, but not visibly so) comes to light under a mask of visibly lighter skin tone. (00:45:05)
Continuity mistake: During dinner after the funeral Streep has a cigarette in her hand. The next shot her hands are together without a cigarette.
Continuity mistake: After stabbing the bad guy at the beginning, Callahan for some reason pulls back and somehow dives past a door managing to drag in a grown woman who was all crouched down by the entrance. Wonky physics of it aside, the bad guy shoot at him, but shoots just a hole in the door frame. The hole appears to be CGI, and in fact when Callahan shoots back from the bedroom, the hole is gone. (00:01:35)

Continuity mistake: By the end of the film, we realise that the Djinn (in this case an invisible and shape-shifting earthly entity of Islamic lore) has staged most of the film's events as a mass illusion. Meaning, the Djinn is a deceiver and can lead humans into dangerous and even deadly situations, but the Djinn cannot perform physical miracles (or else the whole movie would end almost as soon as it started). At the story's climax, the lead characters, Khalid and Salama, end up in the 62nd-floor penthouse of a luxury high-rise, where Khalid drops Salama to her death from the penthouse balcony, just as the vengeful Djinn intended. However, only minutes earlier, we see that the high-rise building is actually still under construction, and it's stated that the building is months away from completion (its main entrance and plate glass have not even been installed). The Djinn only created the illusion that the building was completed to deceive the lead characters. In reality, without electricity and functioning elevators and hundreds of feet of completed stairwells, there was no physical way for Khalid and Salama to reach the 62nd-floor penthouse suite of the high-rise for the climax scene, even if they were being deceived by illusion.
Continuity mistake: When Keisha shows the father the painting she made, the father places it on the table over the color palette. Then after Keisha screams in the father's face, the magazine is gone. He sprays her with breath spray and replaces the painting over the color palette. (01:07:00)
