The infamous night vision sequence was actually a re-shot version of the scene. After realizing that they shot the original version of the scene to look too dark, filmmakers had to return and re-shoot the entire sequence, delaying the movie's release for six months. Due to the issues with the budget, this scene could not be finished properly, thus it was decided to add green visual tint to the scene to make the scene look like it was shot in night vision, despite the lack of point in giving it that look.
