Other mistake: Roma is shown making phone calls, even though the robbers are said to have stolen the phones.

Visible crew/equipment: When Levene is on the phone to a sales prospect he says "Danny that piece of property I had for you has increased in value, Grace, Grace what was that figure? Seventy-six thousand dollars." During that time the boom microphone is visible at the top right of screen. (00:22:00)
Ricky Roma: You never open your mouth until you know what the shot is.
Trivia: Though Alec Baldwin's character never introduces himself, in the script his name is Blake.
