Continuity mistake: When the girls start doing CPR on Cassie, there's a strand of hair running along her forehead. A shot later, it has a different style and is closer to the top of her head. (01:44:20)
Factual error: After the naval battle, Thraex is waiting for an informant who tips him off about Lucilla and Marcus Acacius's plans. And of course, as a well-educated gentleman of 200 AD, he kills time by reading the newspaper. Wait, what? Needless to say (to anyone but Ridley Scott, probably), ancient Romans wouldn't/couldn't exactly get their news by newspaper, the press having not been invented yet. This one looks so modern in its layout it even has headlines and a proper publication title, "Roma Viridia."
Continuity mistake: After the bad biker bites Noel, he removes the rearview mirror from the windshield and smacks the bad biker with it.

Other mistake: When Ryan is live streaming his magic show, the amount of likes is always way higher than the amount of viewers, which is quite impossible. (00:01:07)
Continuity mistake: When Manhattan starts to freeze, the car speeds through the streets with Callie and Phoebe in the copilot's seat. In the close-ups, one can see that the place is empty. In some shots, there's a shadow of a bulky object, maybe a dummy of some sort or the driver, but it's definitely not the two actors.
Continuity mistake: When Lagrange finishes dancing with Argylle, she places both hands around his back, the left over the right. A shot later, they're placed the opposite way. (00:02:10)

Continuity mistake: When Deadpool and Wolverine are eating a burrito, Deadpool throws his on the ground a few feet to the right. In the aerial angle the burrito is gone.

Continuity mistake: When Axel introduces Serge, he places his hand next to his ear as if he were hard of hearing. From the opposite angle, his hand is lowered. As of then, the position of his hands is not continuous between shots.
