Continuity mistake: When Eduardo finds the letter on the mantlepiece about them apparently stealing the idea for Facebook and asks Mark if they did or not, he places a bottle on the mantlepiece just before he finds the letter. This bottle rotates slightly between shots without him touching it after placing it down. (00:49:15)
Continuity mistake: When Elizabeth meets Lionel for the first time, her face netting disappears and reappears between shots.
Continuity mistake: Just before Secretariat's first race, the main characters are discussing tactics in the parade ring. In the background is a jockey in pink and gold colours standing by his horse. When the shot changes angles he is mounted and being led out onto the race track. This means that he would have only taken one second to mount and travel a distance of about 10 meters. A couple of shots later he suddenly appears again, but this time he is being led into the saddling-up area, even though the jockey is already on board.
Continuity mistake: After Rita and Eddie's fridge is repossessed they are arguing outside their flat. On the wall outside their neighbours' flat there is a wheeled trolley or pushchair hanging on the wall. This disappears and then reappears several times during this sequence of the film.
Continuity mistake: When the hijacked DC9 aircraft arrives into Algeria for the first time, in a front shot when taxiing, the nose and windshield are of a Boeing 727. Afterwards it becomes a DC9 for the remaining of the movie.
Continuity mistake: The little Nono is singing the nursery rhyme in front of the cafè. One of the nazis tosses him a coin, while the other puts the cigarette down, but at the cut he's already taking a puff.
