The Dark Knight – Chased by the Camera
During a scene in The Dark Knight where the Joker (played by Heath Ledger) is being chased, a cameraman and camera can be seen reflected in a window. This mistake is particularly noticeable because it’s right in the middle of an intense chase scene. The cameraman and camera are visible for only a few frames, but it’s enough to take you out of the story. It’s unclear why the filmmakers didn’t catch this mistake during post-production, but it’s likely that they were focused on the action rather than the reflection in the window.
