Continuity mistake: When Constantine manages to get the mirror through the window he falls on his back. To the right on the screen a chair lies on the floor beside a dresser. A few shots later when it cuts to Constantine getting up we can see the chair has changed position as its back now covers the opening of the dresser. (00:08:15)Mortug
Continuity mistake: In the scene where Aladdin is talking to Jasmine in front of the mirror the jewelled flower is in a vase with a real flower when the monkey under the table takes the real flower and the scene cuts back and shows the vase with both flowers. Seconds later the vase is completely empty.
Factual error: In the final fight scene with Malekith, Thor falls through a portal that brings him to Charing Cross station, where the lady on the train tells him he has to ride 3 stops to get to Greenwich. Charing Cross is not on the Jubilee Line and so not directly connected to Greenwich - even then it's a lot more than 3 stops. (01:33:45)
Continuity mistake: When Jingle, Jangle, and Mrs. Claus pay a visit to Mother Nature, Mother Nature calls her sons beside her - Snow Miser and Heat Miser. She then turns to Snow Miser and asks him to allow a little snow fall in the South, and then turns to his brother, Heat Miser, and asks to allow just "one Spring day at the North Pole." The words are correct dialog, but she should have said each of those lines to the OTHER brother. (00:39:40)
Continuity mistake: There is a scene about 2/3 of the way in the movie where you see Jamal (Martin) standing by the lake and his chain is under his shirt, he looks back into the forest and his chain is hanging out of his shirt, then he goes back to the lake and his chain is under his shirt again.

Plot hole: When Astrid gets on Toothless for the first time, Toothless takes off uncontrollably and tries to scare her. Hiccup seems to have no control over him at this time. How is that so if with the new tail fin, Toothless cannot fly without Hiccup's precise control of the tail fin? That whole sequence would have fallen apart. This mistake was even admitted to on the DVD commentary. (00:53:35)Quantom X
Character mistake: At the memorial service the principal says that it's been 39 days since 39 loved ones had died. But there were 40 students on the plane and 4 chaperones, making the total 44. Now 7 people got off the plane, which means 37 people related to that memorial service actually died, not 39. Two pilots would make up the numbers, but there would be flight crew too, which still leaves the numbers off.
Continuity mistake: In the scene where Charlie and the snowman (his dad) are getting chased by the bullies, the sled gets split in half into two sled pieces. But you can clearly see that in some parts of this scene, Charlie is riding a real snowboard, and in others he is riding the half piece of sled.
