Continuity mistake: The scene where Hesh and Massive Genius are sitting down and drinking. Massive Genius has just requested that Hesh pay reparations money. Paulie then steps forwards, aggressively demanding "or what?" Behind him, Chris is standing by the white pillar. However, two shots and 2 seconds later, when the camera cuts back to Tony's holding Paulie back, Chris has completely disappeared from the veranda - he is neither behind Paulie or Silvio.

Continuity mistake: Adriana was wearing a red blouse at the Crazy Horse, and in the car with Tony during the accident. When Christopher picks her up from hospital, she is wearing a gray Fila sweatsuit jacket.

Continuity mistake: During FBI questioning, Adriana vomits on the conference table. Bureau Chief Cubitoso is sitting to her left, and in the scene, he has no vomit on his clothes or face. However, in the next close-up shot, he has vomit on his shirt and face. (00:51:23)
Continuity mistake: During FBI questioning, Adriana vomits on the conference table.
