Continuity mistake: Walter tore out the newspaper article ("Body of Woman Found at Greenland Rest Stop") fairly neatly/evenly; it was relatively straight across the top, though a little jagged as could be expected. When Walter looked at the article some time later, the jagged top was worse and there was MORE space between it and the title. The right side also appeared to be more jagged than it was and include a little more of the article that was to its right before being torn off. (00:07:03 - 00:13:37)
Continuity mistake: After their fight with the monkey Sara has some scratches on her forehead and cheekbone but when she gets to the castle with Freya they are gone.
Factual error: When Anita Hill is in her hotel room waiting to testify she is watching the Texas v. OU football game. In the movie the date for that scene is Friday, October 11, 1991. The Texas v. OU football game was played on Saturday, October 12, 1991.
Factual error: The movie puts a caption in the prologue "January 2013." Later the protagonist puts the hammer he received by the mysterious delivery right on top of a newspaper, a copy of "Mid-Day" with a retouched opening article (related to the movie murder of course) but headline news with a Sunil Gavaskar quote that dates it as a December 2015 edition.

Factual error: In the Templehoff Airport flyover scene there are Soviet era Antonov An-12 propeller driven aircraft on the tarmac. These were first used by the Soviets in 1953.
Other mistake: When Bill is alone with the girl at his house, there is a roaring fire, but in the next scene the fire is completely out and he comments, "you must be cold, I didn't have time to start a fire".
Continuity mistake: When they are at Sarah's house, the boy's father tells her to go outside and ask Lucas to pull the van around back. When Sarah walks to talk to Lucas her long braided hair is tucked into her shirt and her arms are crossed. In the next shot when the camera comes back, her hair is on the outside of her shirt despite her arms still being crossed. (00:45:55)
Factual error: The Budweiser beer bottles used in the movie have the 'Bud' neck label, not used on bottles in 1985.
Continuity mistake: John Biswas is tailing the little deaf girl. His scooter breaks down and he follows her on foot. They are walking in the same road in two different shots, with a cut just a few meters apart. The toys in her right hand and the paper in her left swap hands in the second shot. (00:18:20)
Factual error: When Steve Carell is telling his nephew Jesse Eisenberg that he is leaving his wife, the view from his 1930s era Hollywood Hills home shows the modern skyscraper-filled LA downtown skyline.
