Factual error: Attorney Aegis inappropriately rounded up/down a couple common statistics pertaining to the infamous Ford Pinto case, which resulted in a total that didn't add up: "it would cost the company $11 per Pinto to fix the problem. But with 12 million [should be 12.5] of 'em on the road, that would cost $137 million compared with $50 million [should be 49.5] to maintain the status quo. $137 million to fix a $50 million problem..." But 12 million x $11 = $132 million [not $137 million]. (00:24:38)
Factual error: This is set in 1966. The soldiers are all using the Aussie version of the M16 which was introduced in Vietnam by their military in 1967 with limited use and only became more widely used somewhat later.
Suggested correction: There's no such thing as an Aussie version of the M16, they were all made in the USA by Colt, or its contractors. I assume the poster means the M16A1, identifiable by the bolt assist lug on the right hand side and closed flash suppressor.
Factual error: At presentation of the Medal of Honor, the US Air Force Secretary reads the citation that states William H. Pitsenbarger was an Airman First Class (E-3 with 2 stripes) but in the battle scenes William H. Pitsenbarger is wearing the insignia of a 'Buck' Sergeant (E-4 with 3 stripes). (00:14:29 - 01:43:55)
Continuity mistake: Right at the beginning, two dumb kids looking for drugs are forced to make a spontaneous donation to the cult. Before the stream starts the pink polo one does not have the scooter on his shoulder, which is back when the stream starts, then off again.
Continuity mistake: The tassel on Molly's graduation cap disappears at the end of her speech, then reappears later.
Factual error: The protagonist wakes up supposedly at 5 AM of December 2nd in New York City. Outside, the sun is shining, almost two hours too early. (00:00:15)
Factual error: In 1915 Tolkien was commissioned as a Second Lieutenant with the Lancashire Fusiliers. He (plus various other officers) is constantly shown in the film wearing bright metal cap badge, collar badges and shoulder titles on his Service Dress tunic and greatcoat. However, in the Lancashire Fusiliers officers did not wear shoulder titles on their SD tunics/greatcoats, and their cap/collar badges would have been in a darkened bronze finish, not bright metal (which was for Other Ranks and NCO's).
Other mistake: The opening (like most of the movie) does not make much sense, so you can pick your kind of mistake here; the special effects are cartoonishly bad throughout the big firework explosions. When John Abraham is knocked through a window by a rocket (which takes off with a 270° turn without even rising) to the face, he gets up unscathed and starts screaming for Junky and Chandu. The camera moves from them to him and he's running with the girl in the red costume in front of him (which was way behind, safely, when he crashed through the window, so already that is wrong), and then there's a wider shot. In that shot, you can tell that Adams is bumping into the same people as before and the distances between the extras are all wrong. (00:06:35)
Revealing mistake: It was pouring when Adam, Hannah, and Megan got out of their SUV to talk to the Man and try to get help with the flat tire. As they stood there, no "rain" was hitting them and it became obvious that their partially wet-looking clothes were "pre-wet" - they returned to the SUV with the same amount of "wetness." Also, the rain was coming down in straight streams, all parallel. (The water flow appeared to be slightly angled to make the artificial "rain" look more natural).
Continuity mistake: The amount of blood on 10-year-old Miguel's face and neck after his "jump in" is not consistent. Sometimes there is more (or less) blood on his cheeks and neck and sometimes it appears splattered compared to large areas diluted with blood. The intensity/color of the blood also changes - sometimes it is very red but other times it is paler. The cut on his left eyebrow apparently was not on the far left corner yet sometimes the blood started there; other times, the blood started almost to the middle of his eyebrow. Sometimes he has blood below his eyebrow. Despite all the blood on his face and neck (down to the sagging T-shirt), there is no blood on his white or light grey T-shirt. He also does not get any blood on his jacket. Miguel was repeatedly punched then kicked by several large, muscular adult gang members for 13 seconds (to become a member of the MS-13 gang) but is unrealistically able to get right up then go and pick up and carry his dog - with no limping or signs of pain. (00:29:15)
Continuity mistake: In a flashback inside a pub, the protagonist writes his number on a coaster to hit on the waitress. During the scene, the coaster changes position repeatedly between shots. (00:25:55)
Continuity mistake: After Amy asks Laurie why she shouldn't marry Fred, her right hand moves from the edge of her sketchpad to the center. (01:15:37)
Revealing mistake: When Anita goes to destroy their getaway car you see her pour gasoline all over the roof and hood. Then when she lights it on fire it's only burning inside the car. (01:06:40)
Continuity mistake: Scooby and Shaggy are lying face down on the massage table when the zombies arrive. Shaggy has his robe lowered baring the upper back, but in the close-ups you can still see the robe up covering his shoulders perfectly. (00:28:00)
Continuity mistake: After Wesley has intimidated the snot bully, he comes back home and finds the police. Sitting at the table, his mom holds his arm and says "Wesley, Mr. Chambers asked you a question." Mary Elizabeth Winstead has her right arm on the table, close to her body. Change of angle and she is holding the coffee mug instead. (00:45:10)
Continuity mistake: The dorky protagonist just bumped into the bike shop girl. She tells him "It's all good, man", to which he replies asking how's the bike. Behind him, a woman with a dog makes her appearance. Over 10 seconds of conversation pass, and the woman is still where she was, but in the shot that follows, when she says "I'm Cate, by the way", the woman warped past him, and is now behind her to the opposite end of the sidewalk. (00:07:15)
Continuity mistake: Phil put 7 bottles of "Ouzo" in his basket (and left two on the display). When he was driving away, there were 11 bottles of "Ouzo" in the box on his seat. Also, when Phil was drinking on the bridge, the "Ouzo" was dark-colored (but "Ouzo" is clear or cloudy white). (00:15:32 - 00:24:14)
Factual error: During the opening credits, Alec Baldwin and Selma Hayek are driving back to New York. They pass by various buildings, one shot being entirely devoted to a dilapidated Blockbuster video store. That shot must have been archive footage from the UK, since you can see the realtor sign by it, and it's from Carter Jonas, a London based firm, and gives an 01962 phone number (Windsor).
Continuity mistake: When George gets shot, he lies flat on his back. When Gloria walks in on the scene, there's a closer view of him and he is lying on his side. (01:18:45)
Continuity mistake: When we see Erin and Leah for the first time, they're talking and smoochin'. Despite the conversation being continuous, the reciprocal position of their hands changes abruptly between shots at the beginning (Erin's hand is on the outside of Leah's, then on the inside, then outside again).
