Goofs

A man throws coffee dregs onto Niklas's stomach early in the movie, when he is wearing suit trousers, a vest and suit jacket. Later in the film we see the coffee stains on the front of his blue shirt. The stains are not blurs, as they would be if they had soaked through the vest -- they directly have been thrown at the uncovered shirt off-camera, to create the coffee stains we see on the shirt.

Note: this extreme trivia is necessary, because the film has such good continuity, I couldn't find any significant mistakes. Its geography, time & distances (airport, lower Manhattan, Gowanus Canal-Brooklyn) are extremely accurate.

Tisha's apartment building is at the southwest corner of Bond St. & 4th St. in Brooklyn. Her windows face south, looking at the F & G trains' elevated track. In one scene, Niklas walks to this window and looks down, and the view is a view from the North side of the building, 4th Street. In reality, he would only have been able to see the Gowanus Canal in the back of the building -- not 4th Street in the front of the building.
