Continuity mistake: When Penelope is sunbathing whilst Paul is on his laptop, she is face down with her head touching the lounger, but in the next shot, her head is suddenly raised above the lounger, then back to leaning against the lounger in the next shot.
Continuity mistake: When the two protagonists are introduced to the private room and watch Dan's video message, the clock in the background never moves despite the several minutes duration.
Continuity mistake: When the young boy loads his bow and arrow while talking to his older brother, he does this twice without firing it. (00:53:55)
Factual error: Ann plays an organ in a church with no electricity. And no, there was no manual bellows to make it work; the movie makers simply didn't know the difference between the operation of an organ versus that of a piano.
Continuity mistake: Théo shows up in class unannounced. The teacher tells him to sit next to "that girl", mistaking Daniel for one. The classmates of course have a cackle at that; the girl at the desk behind Daniel's laughs holding a pen in her left hand at first, right hand at the cut. (00:08:50)
Factual error: Summer and Carmen are at the saloon and catch on the local news the report of the kidnapping. The scene is set in Tuscany, Italy, but the news anchor is Spanish actress Paz Vega, speaking with an obvious accent and mispronouncing words. To make the whole situation even more absurd, she is supposed to portray a native Italian speaker, "Giulia Carni": the last name is Italian sounding but nonexistent in reality, and the headline used for the news report, "Nonna-napper", "kidnapper of grandmother" has such an awkward and unnatural sound and feel in Italian and for an Italian audience, that nobody ever would use it. (00:37:50)
Character mistake: The protagonist is reading the review of his book "Bitter Tulips." The influential literary critic publication apparently has zero proofreading, since the article says that the novel "can be described as AN failed experiment." (00:45:00)
Other mistake: The town is Mt Barker. The red and blue ribbons on the sheep pen say Mt Baker.
Continuity mistake: The handful of yams (pureed) that Glory throws onto the left side of her bowl is spread out, relatively flat, and spans close to the bowl's rim. Suddenly, the yams are piled higher and further away from the bowl. The yams on both sides appear to vary, but other views are too short to be confirmed (without pausing). (00:48:11)
Factual error: The timeline is completely wrong. The film begins in 1902, at which point Gertrude Bell has just left Oxford and is about to go to Persia. In fact, Bell was 34 in 1902 and went to Persia ten years earlier, in 1892. By 1902 she had already been travelling for a decade.
Factual error: A library assistant is showing his cellphone to a Fed. The Fed pulls out his gun and shoots the assistant from about 8 inches away into his left temple. Another Fed, standing to the immediate right of the assistant is shown after the shot. But there is no blood or material spray on him at all. His white shirt is immaculate. In fact, there is no blood anywhere.
Other mistake: When Otto Preminger calls Trumbo from his car to announce that Trumbo's real name would be credited for Exodus, Preminger tells him to look at the front page of the New York Times. The problem is that Trumbo has already picked up the paper from his counter and is reading before Preminger even tells him which newspaper features the article.
Factual error: The military policemen wear plain black armbands. Their armbands actually had 'MP' in red letters.
Factual error: Throughout the film, the helmet plates worn by the London Policemen are the 1930's pattern with the George V cypher in the centre. In 1912/13 they would have repeated the officer's collar number in the centre. The helmets themselves are also British military pattern blue cloth helmets with Police fittings added, rather than the correct Police pattern ones.
Continuity mistake: Near the beginning of the movie when Joy is in her airline's company uniform and getting ready to go to work, the knot on her scarf changes from loose to tight several times in the different shots.
Character mistake: The girl scores a goal in the soccer game but it does not actually go into the goal, so everyone is celebrating a miss. (00:02:00)
Revealing mistake: In the shot where Laing hears the horse neigh, at the top right corner of the screen that there are trees on the other side of the wall, where only the blue sky was before. (00:19:15)
Revealing mistake: At the cocktail party in his honor, Rita Richards introduces herself. Joaquin Phoenix's scotch is in a transparent plastic cup, and you notice what happens in most movies, here with particular clarity; when he brings it to his mouth, he does not take even a sip, but just pretends. (00:06:05)
Visible crew/equipment: When Davis comes out from the train with the headphones on in the subway just before starting to dance, a cameraman filming the scene can be briefly seen reflected on the train door's glass. (01:08:00)
Continuity mistake: At the very start of the movie as the 2 guys walk down the alley way, the one in the black jacket lifts his arm up as he passes the rubbish bin. In the next shot from the front both his arms are in his pockets and the rubbish bins completely disappear. (01:00:00 - 01:01:00)
