Revealing mistake: During the song "Mark it Up", when Pavi supposedly snatches the panties/thongs off of the two girls, you can see they are already in his hands before he does so.
Revealing mistake: During the final shooting, a bullet hits a lamp post, causing a spark. A grey tape glued over the original metal surface is noticeable to help produce the spark.
Revealing mistake: When the Dreadnought blows up the Buick Riviera, it's plain to see there is no engine or transmission in the car when it flips up and forward.
Revealing mistake: When the double-decker bus flips over Roland, the bus has no passengers and the driver looks very much like a dummy.
Revealing mistake: In the nursing home when Budlofski and Matheson are looking for Saul, we see Saul break a coffee pot over Matheson's head. When the coffee pot breaks you see coffee splash across the top of the camera.
Revealing mistake: When they are sitting down for dinner at the old lady's home, it is clear that a very white light source is in the room brightening things up - something that non-electric oil/kerosene light sources cannot do.
Revealing mistake: When the Porsche Cayenne is lifted out of the water at the scrap yard then placed on the ground, if you look through the gap between the front passenger wheel you can see the engine is removed from it.
Revealing mistake: During the scene when Mary is in the hospital and she flatlines, if you look closely at the screen of the monitor the reading says "leads off" meaning that the cardiac monitoring wires are unhooked from her body.
Revealing mistake: While Frost is on the hotel balcony talking on the phone to Brennan, it is clear the phone receiver is not attached to anything.
Revealing mistake: At the end of the movie when Bryan is fighting the guy with the blades on the yacht, the part where Bryan jumps over the couch you can obviously see it's a stunt double. The stunt double looks Chinese, he has black hair and slim while Bryan looks bulky and has light brown hair.
Suggested correction: In whole fight sequence with the guy with blades Bryan never jumps over the couch. He did it while the black guy was shooting at him, and even then he never looked Chinese.
Revealing mistake: In the auditorium, when Tea Leoni is giving her speech about Pepe the mummy, Greg Kinnear (who is not visible to anyone but Ricky Gervais) starts yelling and Ricky Gervais gets up to walk away. As Greg Kinnear is yelling, an extra a few rows up turns to look at him. That shouldn't happen because the whole plot hinges on the fact that no one can see or hear these people besides Ricky Gervais.
Revealing mistake: In the scene at the morgue, after Amy Smart's death, Keith Sutherland is holding her hand before putting it under the sheet. Her hand should be cold, but when it's moved a hand print is left on the steel slab due to condensation from her warm and very much alive hand. (01:36:45 - 01:37:55)
Revealing mistake: While Punisher is killing Pittsy, you can tell he is holding a dummy, not the real girl.
Revealing mistake: When Fish goes flying off the van, the mat on which he lands is visible. (In subsequent shots, it is gone.). (00:06:55)
Revealing mistake: When Angie is having her ultrasound, if you keep an eye on the monitor, you can see that the baby shows up before the doctor places the reader on Angie's stomach.
Revealing mistake: When Louis is trying to get Lester to apologize to Cleo after hitting her, lots of extras on the sidewalk and across the street can be seen watching the whole scene being shot.
Revealing mistake: When Jared is first reading the field guide, in flashback, there is a shot of Mulgarath in crow form trying to take the book from Arthur Spiderwick. Later in the movie, when Jared is about to burn the book, the same shot of Mulgarath is used again.
Revealing mistake: When they meet up for dinner (Aldous, Sarah, Peter and the hotel clerk), the restaurant host says he is sorry that they have to wait 5 minutes, and you can see that Sarah is obviously way shorter than Aldous. From the front, Sarah comes up to Aldous' eyes, but when they cut to the back, she is almost below his shoulders. Then when they start walking, she steps off a platform of some sort. They seemed to make her taller for just that frame, and then when they are walking throughout the movie, they don't seem to compensate for the difference.
Revealing mistake: During the first scene of Revolutionary Road, when the main characters are walking out of the school, I noticed smoke detectors on the ceiling.
Revealing mistake: During the helicopter escape scene before Tran fires the rocket at them, you can see Cody's hair showing up a bright green from the green screening. You see it several times, but most pronounced at the moment he and Portnoy see Peck arrive with the TiVo. (01:36:10)
Suggested correction: Actually it's from the overhead Plexiglas windows in the Huey. They are tinted green to cut down on sunshine. Any light shining in from above is going to make things appear green.
