Revealing mistake: When Austin enters the bathroom at the casino, keep your eyes on the door during the scene - it opens by itself before closing. (00:31:10)
Revealing mistake: Though it may be a little hard to see, when Poe is in his prison cell towards the beginning, he is doing handstand pushups. This would be really cool to see a star doing these only, you can see the strap around his foot holding him up. (00:07:25)
Revealing mistake: There is one scene where Alicia Silverstone is being taken away, and in the window, in the background, you can see a metro train with the letters on the side stating BC Transit and a picture of the British Columbia flag. Yet, the whole movie supposedly takes place in Washington state.
Revealing mistake: In the big speedboat scene near the end, when Cage is hanging off the side of the boat the stunt double is obvious in wide shots, where the entire boat is visible from above. He has big long sideburns, which are in stark contrast to Cage's short hair, visible in closer shots. At various other points in the movie, stunt doubles appear of much different physical builds than the two actors, with markedly different hair colours, and I seem to recall that at least one of them had facial hair.
Revealing mistake: When Franklin leaps out of the helicopter into the water, there is a shot from above that we see he is about to hit the water. To the left of him in the water you can see the water being split by a helicopter close to the water. The waves wouldn't have been created from the helicopter he just jumped out of because, a)The helicopter was too high up to make that sort of marking in the water and b)The waves are being made to the left of the helicopter. If it was the helicopter Franklin jumped from the markings on the water would have be directly below him or below the helicopter.
Revealing mistake: In the scene at the end, at the Newberry house, where Blank and Grocer meet in the kitchen, you can see that Blanks weapon is empty but he keeps shooting with it. It goes empty when he reaches over the counter to shoot at Grocer, but he still manages to shoot the two persons coming in through the door from the garden afterwards without reloading.
Revealing mistake: When Gere is trapped in the police car and the assassin attempts to shoot him, he fires several shots into the window at Gere's head and every single shot misses yet they do not strike his lawyer or the other window. Where exactly did the bullets go?
Revealing mistake: During the flashback scene where Max is describing the night of the kidnapping, the rainfall at the marina is obviously fake. The "rain" is being blown at an odd angle from an off-camera fan, and the surface of the water is practically still with no raindrops. (00:40:50)
Revealing mistake: In the locker of the Gentleman Caller there are multiple newspaper clippings. When Cross looks at the one talking about his niece, it just does not talk about his niece. The clipping is on camera long enough to be able to read without freeze frame, and it's talking about things like police brutality and apartheid (actual word used), entirely unrelated to the fake headline and picture caption.
