The camera soars over the suspension bridges and skyscrapers of Philadelphia, but the simple act flipping the picture upside down works beautifully to achieve just the right mixture of unease, tension and, well, fun that the movie needs.
However, the rest of the film, I'm sorry to report, just keeps going downhill from there. This movie was not screened for critics, but it is not nearly bad enough to warrant that particular move by the studio - that's usually reserved for real turkeys.
Below, the trailer gives you a taste of those opening visuals, but seeing it on a big movie screen is more impressive, or at least it was for me. Save your money though.
