Continuity mistake: When Nick first enters Sloane Curtis and is talking to one of his male co-workers, in the background there is a man in the typing away at his computer. He gets up and walks off, then the camera angle changes for a few seconds. When it returns, the man returns to his computer. It cuts away and returns a few more times, rather quickly, each time showing the man returning to his computer.
Trivia: The fictional childhood of Nick, growing up in a burlesque club surrounded by beautiful, nearly naked women who adored him, is bizarrely similar to the actual childhood of Alan Alda, who plays the boss character. Alan Alda's father ran a burlesque club, and apparently the strippers and dancers treated the young Alda as a mascot, even keeping him in the changing room as they got dressed. However, as an adult Alda became an activist for feminist causes, rather than the chauvinist effect it had on the fictional Nick.
Trivia: You may have gotten a twitch of deja vu when he exited the building in the rain, with the camera facing south toward the Chicago Board of Trade building. The scene was located in the exact same place, on the exact same corner, in front of the exact same building as a scene in Payback (albeit without the paper vending machine to put a gun in).
