Continuity mistake: When Daniel Radcliffe presents a special item he has put on white gloves, then a second later his gloves disappear. He no longer handles the item with gloves throughout the rest of the movie.

Plot hole: How does the little girl Nina know Ferdinand's name if only the animals can communicate with each other? They're all calling him Ferdinand before she "names" him that.

Continuity mistake: When Marty arrives in 1955, he lands on Peabody's farm and rams through the pine tree he then hits a scarecrow which flies over the top of his car. Then as they show it from the inside the scarecrow slams into the windshield - but how can it slam into his windshield if it is already over the car? (00:31:30)

Deliberate mistake: In the pitch dark mansion dining room, the approaching zombie's screams are instantly interrupted by silence whenever the flame from Chris' lighter goes out, and then the screams instantly resume when the light returns. While this is obvious artistic license, for the record the level of darkness would have no bearing on whether we can hear the zombie screaming.

Factual error: In the first scene where Dr Strange is preparing for surgery he uses improper surgical gowning technique breaking aseptic protocols. Strange puts on a mask after washing his hands, contaminating his clean hands by bringing them in proximity to the non-sterile environment of his face. Surgical masks must be worn before the full washing of hands. Another error is that he inserted his hands all the way through his gown to don gloves. Hands must never leave the sleeves and gloves must be put on with the sleeves still covering.

Herb Brooks: Red line, back. Blue line, back. Far blue line, back. Far red line, back. And you have 45 seconds to do it. Get used to this drill. You'll be doing it *a lot*. Why? Because the legs feed the wolf, gentlemen. I can't promise you we'll be the best team at Lake Placid next February. But we will be the best conditioned. That I can promise you.

Factual error: The size of the shadow of an object depends upon its distance from the light source, not the surface it falls upon. Lifting the cutout of the bird a few inches closer to the sun as they do would make absolutely no difference to the size of its shadow, yet it quadruples in size.

Question: In the scene where the dad tells Annie, pretending to be Hallie, that he is going to marry Meredith, Hallie yells a bunch of stuff in French. Does anyone know what she was saying?

Continuity mistake: When Moana is throwing sticks into the ground, after she starts singing, look back at that spot and all the thrown sticks have disappeared.

Trivia: During the opening fight scene, Comedian throws a mug at his attacker, but misses. The mug strikes the numerals on his apartment door, knocking the '1' off. This turns 3001 into "300", the name of the director's previous hit film.

Other mistake: When the stormtroopers break into the control room, the stormtrooper on the right of the screen hits his head on the door frame. On the DVD release they've added a thump when he hits it. (01:18:55)
