In the first teaser trailer, on the TriStar Pictures logo, after the Pegasus stretches its wings, the background flashes into New York City background with thunderstorms leaving the text and the Pegasus intact for a brief second before the screen flashes again. The official trailer meanwhile had the same logo, but it flashes in the negative effect twice as the Pegasus stretches its wings. the TV spots and the actual film on the other hand, uses the normal variant.
Various effects that appeared as green film scratches (but were not, in fact, scratches) showed up periodically over the credits.
