Revealing mistake: When the American pilots flying P-47 Thunderbolts are attacked by German fighters, the German planes are really American P-51 Mustangs painted with German markings.
Revealing mistake: When Liam Neeson is on the boat on his return from England there is a shot of the water and part of the boat where you can see a modern CCTV camera on the side of one of the masts - rather advanced for the time the film was set. (01:21:20)
Revealing mistake: In the shots taken from above, on the scene where Mallory and Stavros are climbing the cliff under hard rain, the rain falls over the back of them, not over his head. Reveals that this scene was taken in horizontal position over the floor. Not taken in vertical position.
Revealing mistake: In the scene where the women are laying in their bunks in the work camp and one lady is describing what she heard about the horrors of other concentration camps, at the end one woman puts up her hands to her face. You can see her fingernails are neatly manicured, something you'd think wouldn't be possible in a forced labor camp.
Revealing mistake: Allison is wounded by a grenade fragment while disabling the Japanese 105's. But when his bloody shoulder is first seen, the blood stain is visibly too bright for real blood.
Revealing mistake: Gruesome but wrong. When the other pilot is murdered, the killer shoots him in the neck pointing downwards, but the spray of the blood-pack is from his forehead up high. (00:31:20)
Revealing mistake: When Tristan kill the guy in the liquor storage and the hay fork goes through his chest, you can see that parts of the hay fork's tines closest to his body are not covered with blood. (01:51:05)
Revealing mistake: When we see the navy seals burst into the factory to rescue the pilots, several of the bad guys get shot. On one of the bad guy's feet who falls back onto a table, there is a rope attached to his foot obviously so he wouldn't fall to far, or not to hurt himself or something. (00:09:50)
Revealing mistake: When Mandras is being treated, following his long trek back to the village (he has apparently walked barefoot), the tops of his feet are covered with blood and dirt. When he is laid on the table by the doctor, the soles of his feet are facing camera, and they are clean and white.
Revealing mistake: After Richard has accepted that he will be king, he appears before a large assembly. Several of the soldiers standing by the walls are obviously plastic dummies. They have unnaturally smooth and blank facial features, and when you can see their hands, they are not grasping their guns, but merely holding their hands stiffly out with the gun between them.
Revealing mistake: When the Ferris Wheel at the theme park has broken from its mounting and is rolling down the pier, it appears to be rolling forward but rotating anti-clockwise when if it is rolling forward it should be rotating clockwise.
Revealing mistake: In one of Renato's fantasies about Malena she comes into his dark bedroom. The light is falling into the room from the hallway, but when she walks through the room she casts a second shadow created by a stage light. (00:16:20)
Revealing mistake: When Alain is holding Guido's dead body and telling Steinkampf that he "died as a Legionnaire", you can see Guido swallow if you look at his throat.
Revealing mistake: During the initial breakout of the Gladiatorial training school an armed guard is stabbed on a balcony and falls to the arena below. He gets up and walks into the doorway adjacent to where he had fallen, apparently satisfied that his part was completed.
Revealing mistake: There is a British pilot who tries to pull rank in order to chat up Erik's sister. He has a hook for a hand, but the arm isn't any shorter. He is holding onto the hook under his cuff.
Revealing mistake: Except for the one that crashes, every single helicopter in this film is 100% factory fresh, brand new - no mud spatters, no scratched paint, not a dent or a blemish anywhere. They look like they just rolled off the production line. Strange that, on the front line in a war zone and all.
Revealing mistake: When Nullah and his mother are being pulled out of the tank, the stitching on the dummy used for the mother is visible.
Revealing mistake: During the fight scene in the village between Elias and Barnes, as they roll around on the ground, Barnes "hits" Elias with a right hook and Elias's head is thrown to the side as if he just caught a serious blow. The problem is Barnes's fist quite obviously clears the front of Elias's face by at least 5-6 inches.
Revealing mistake: When the U-571's crew member starts firing the MG-34 at the survivors in the rowboat, you can see the ammo belt is all blanks.
Revealing mistake: When Jim is riding the bicycle through the empty hospital, the "Frigidaires" begin falling through the roof. One bursts open, dropping its contents onto the floor. Something from inside must have landed on the camera because you can see it jerk suddenly.
