Goofs

After George tells Ricky that the phones were stolen, in frustration Ricky sums up "They stole the leads, they stole the phones... what am I going to do this month?" Up to that point, no mention of the leads being stolen had been made, just some of the contracts.

When Levene enters and exits the Spannel house, the rain is pouring immediately outside the front door. But after he exits the camera pulls back to reveal he is on a large roofed porch. So the rain would actually be falling some distance from the door.

After the police interview Alan Arkin puts on his coat and leaves the office. In subsequent scenes his coat can be seen draped over the back of the chair at his desk. The coat appears and disappears in Jack Lemmon and Kevin Spacey's confrontation over the office burglary.

Shelley pretends to be a client from AMEX when Lingk comes into the office. But when Roma first meets Lingk at the bar, he's sitting with Shelley. Surely Lingk would have remembered who he was.

Right after Williamson messing up with Ricky's deal with a client, Shelley Levene appears in the background teasing him. However, in the previous moments he was in the office talking to the detectives and there's no indication that he got out of there at any point.

Stealing the list of references from Williamson's office constitutes the crime of burglary, but the police describe the crime as robbery. This same mistake was present in the original play.

The cops would not make such a big deal out of a common burglary. They'd make a report and leave. They couldn't and wouldn't conduct a day-long, on-the-spot, investigation while rudely accusing the employees of being guilty.

AIDA is described as standing for Attention Interest Decision Action, whereas it really stands for Attention Interest DESIRE Action. The one Baldwin quotes is nonsensical because the Action is the Decision.

Although the play was set in Chicago and the movie in New York, references are made in the movie to places around or near Chicago. Levene refers to the meeting in Kenilworth which is a suburb of Chicago (Kenilworth is also a New Jersey suburb of New York City, near Newark Airport). Levene also mentions fishing for muskie in Wisconsin. Moss gets angry and says that he is "Going to Wisconsin." Characters in New York wouldn't reference such places.

It makes sense that Roma would get the drunken loser in the bar to sign over lots of money for unseen land, but the loser's wife would not cook dinner for Roma, a total stranger late at night, sign the contract, and then demand that her loser husband go get the money back early the next morning.

At the end, Roma is screaming at Williamson because Williamson has interfered with Roma's effort to mislead a potential client. A police office is standing by taking it all in. However the officer takes no action despite what constitutes ready admission of a serious attempt at fraud.

When Levene tries to convince Williamson to go along with his plan to give him some of the Glengarry leads, the boom mic operator is reflected in the office window.
