Revealing mistake: When making traps, he's harvesting powder from a spent shell (primer has been struck). (01:05:50)
Revealing mistake: Deacon uses "hidden" food to get the dog to come up to him. The "treat" is largely concealed - but the dog's slobber gives it away. The camera shifts after Deacon's hand goes next to the dog's mouth, giving the impression that Deacon is just petting the dog under his neck. (00:06:35)
Suggested correction: He was feeding him. You can see him eating out of his hand. The food isn't "hidden" You can hear the dog sounding as if he were eating something and his face is in his hand. Those were added sound effects in post. At first glance I got the impression he was giving the dog a treat as they were pals.
Part 1: Based on the circumstances plus Deacon's actions immediately before, during, and after his encounter with the dog, I believe it was a lousy attempt at luring the dog but trying to give the impression there was no lure (food). Deacon did not have food when he came out of his house and wasn't expecting the dog to be there. Deacon even pointed his right fingers toward the dog when he said, " You [are] the one [who has] been gone for the last two weeks." Deacon stoops down and [continued].
Part 2:...makes an effort to point his right hand fingers downward, again giving the impression he wasn't holding anything (food). If feeding a hungry, cautious dog, I think he would have displayed the food in the palm of his hand (what is there to hide if actually feeding the dog?). When "sneaking" the food into the dog's mouth, a small piece can be seen falling to the ground. Deacon holds the dog under his neck, probably to keep the dog from reaching the food that has fallen.
Part 3: (The dog later picks up the piece that fell.) Taking all these odd movements into consideration, I'm sticking with my assertion - Deacon "surreptiously" lured the dog, but his actions were noticeable, thereby revealing what was actually happening. Also, if the dog was missing for two weeks, Deacon would not have been likely to bring food out for the dog that morning. Anyone wanting to view the scene and serve as a tie-breaker, start at 00:06:26, watch Deacon's right fingers @ 0:06:32+.
Revealing mistake: When Maurizio has a water fight with one of the truck drivers, above the logo of the fictitious company "Corriere F. Reggiani" on the window of the truck you can see the logo of "F.lli Zucchetto", (Zucchetto Brothers) the real company owning the truck, who organizes real life gatherings of vintage truck owners. (00:22:50)
Revealing mistake: Lower-third shots of the aquarium in the background at the Delaware Raceway's sports lounge were often blurred and did not look like they matched full views of the aquarium. (00:36:05 - 00:36:34)
Revealing mistake: The hubcap on the road that the "Black Saints" boy tramped on was a prop. He stomped on one side of the hubcap in his sock (his shoe had fallen off while running) and the other half that was not under his foot rose into the air. Also, when Harold picked up the hubcap, it was flexible (rubbery) and curved. (00:05:38)
Revealing mistake: The blemish/mole that was on the right side of Ghost's nose showed up on her left side (and she was not looking into a mirror). (00:57:40)
Revealing mistake: Right after baby Estella is born there is no umbilical cord.
Revealing mistake: During one of the chase scenes, an SUV hits a rock barrier and flips over landing on its top. The car spins around, and we see that it is empty. The driver then climbs out as if he was just in the vehicle.
Revealing mistake: Much of the cemetery scene with the Mentor was "green screened." The backgrounds were inconsistent (e.g, trees and tree trunks) and sometimes the Virtuoso's and Mentor's head were practically together when facing each other. The sizes of their heads also varied at times. The Mentor also was at an angle to the Virtuoso during his long speech, at least giving the impression that he was using cue cards to remember his lines. A couple times, the Mentor looked like he lost his place. (00:15:24)
Revealing mistake: The "unnatural seam" (line) across Jimmy's forehead and beyond - as well as the overall appearance of his head - indicates that he is NOT "naturally bald"! His "fake" bald head was not put on nearly as well as those seen in numerous other movies. [The actor playing the character does not have much hair in real life, but he also doesn't have that artifical line across his forehead.]. (00:07:13)
Revealing mistake: The "bridge" within the crime scene tape is obviously a prop. It should be a continuation of the road, but it is tilted to the left and is more vertical (around 45°). The bridge isn't even very high. When Byron and others go under the bridge to look at the dead girl, there is only a few feet above their heads (clearance under the bridge). (00:04:54)
Revealing mistake: At Mrs. (Louise) Bundy's house, Ressler and McChesney were seated at the coffee table, maybe 3' apart. When Louise was sitting in the chair talking to them, only some hair to represent McChesney was on the left side of the screen and Ressler was not visible. It was obvious Louise was delivering her lines without the two sitting there because her head and eyes were turned way too far to the left and right (beyond where their bodies would have been) to be making eye contact with them. (00:45:25 - 00:46:34)
Revealing mistake: DEA Agent Rick Bowden was already seated "in the best position" before knowing where Ross would sit in the SF library. Chris Tarbell already had a surveillance camera behind the seat Ross chose, giving him a clear view of Ross, also before knowing where Ross was going to sit. Even if there were cameras in other positions, the DEA Agent and Chris Tarbell being at the right spots in advance was too coincidental to be by chance alone. (00:02:09 - 00:02:30)
