Maleficent: Mistress of Evil (2019)
Goofs
Character error
Diaval appears uncomfortable with being served poultry, presumably due to him actually being a raven. However, ravens do sometimes eat other birds, so he shouldn't have an issue with it.
Factual errors
In the first movie, Maleficent cursed Aurora, not the spinning wheel spindle, and the curse ended with True Love's Kiss. Therefore, it's impossible for the spindle to be cursed in this movie.
Revealing mistakes
At 8:44, a stunt double is clearly seen in the water after Aurora falls off the log.
Spoilers
Character error
Foolishly, the Dark Fey react to the castle's deadly magical artillery by engaging in close combat, instead of using their powerful flight ability to bombard its defending soldiers with rocks dropped vertically from a great height.
Continuity
When Maleficent is rising as the Phoenix, the two guards run away from the castle turret. When the camera pulls back for a wider shot, they are seen running away again.
Plot holes
After the battle, near the end, the human and Fey fighters embrace. However, the Fey are allergic to iron, and the soldiers are wearing iron or steel armor, so the embrace of friendship would be hurting the Fey.
