In the scene in which Naturelle tends to Monty's facial wounds, Naturelle is wearing a sweatshirt which reads "COVENTRY" (the prep school from which Monty was expelled). Near the end of the scene, Naturelle steps into the kitchen to fill a plastic bag with ice. As she enters the kitchen, her sweatshirt suddenly has two letters reversed. It reads "COVETNRY."
In the scene with Uncle Nikolai he cocks the handgun on his table, which pulls back the hammer. Monty is then given the gun, and when he puts it to Kostya's head he pulls back the hammer again.
After Jacob finishes his champagne at the table at the dance club while drinking with Monty, his glass suddenly refills itself.
When Monty writes his name on the window he makes the top of the "Y" very narrow; as they are driving the top of the "Y" is wider.
When Mary and Mr. Elinsky are sitting alone Mary's hair is continuously hanging down in her face. At one point she sweeps it behind her ears, but when the camera cuts back her hair is hanging just as before.
In the interrogation scene, the DEA agents inform Monty that he will sentenced under New York's draconian "Rockefeller Drug Laws." But given the arrest by a federal agency (DEA), prosecution by the U.S. Attorney, and sentence to a federal prison (Otisville), the case is clearly federal. New York law would not apply.
The scene in which Frank is awaiting for the Unemployment data shows a New York City afternoon time of 2:15pm. Unemployment rate information data is released on Friday morning at 8:30am New York City time.
The age of consent in New York is 17 so when Naturelle asks Monty what if she was really 17 rather than 18, his response of how it might change things doesn't make much sense.
When Monty expresses his disgust against Pakistan originated immigrants, the magazine cover placed on taxi cab's cabinet beside a Pakistani flag wasn't a Pakistani one, rather it was a Bangladeshi tabloid with Bengali font and their actors in it.
When "uncle Nikolai" points a gun at Monty saying that "it never jams"- it actually jams. When he cocks it you can see that the slide is open and when he turns it you can see that there is a round sitting sideways in ejector. His scene partner looks at it, his attention drawn to the gun.
When Monty expresses his disgust against Pakistan originated immigrants, the magazine cover placed on taxi cab's cabinet beside a Pakistani flag wasn't a Pakistani one, rather it was a Bangladeshi tabloid with Bengali font and their actors in it.
The tattoo on Nikolai's hand means "I'll survive" (not "to survive" as he says). Besides, it is misspelled (in the 3d letter).
When Kostya is waiting outside Monty's apartment catcalling the women that walk by, he refers to himself as Russian: "I make you half-black half-Russian baby" We know from other scenes in the movie that Kostya is Ukrainian and does NOT like to be confused with Russians.
