At the beginning of the film, when Jakob starts chasing the paper, it is clearly light outside, even though it is 7:30 pm in the winter in Poland. Then, 25 minutes later, when Jakob told to go to the police building, it is quite dark. In the winter, the sun would have completely set hours before.
The train locomotive in the lower left-hand corner of the DVD cover artwork is correct for southern California when the movie was released in 1999, but it's totally wrong for the movie's setting in 1944 Poland. Its cab profile was used on various diesel-electric models built by General Motors for the North American market from the early 1960s onwards, it has 1990s-style dual low-mounted safety lights, and its red-and-gray paint scheme bears an uncanny resemblance to that used by the Southern Pacific Railroad in the western United States in the late 20th century.
