In the kitchen scene where Armand and Val realize Agador never prepared an entrée, Armand slips and falls while bringing the sweet & sour peasant soup pot back into the dining room; as he then tells Val "go, go, she'll be here any minute, go", he is clearly laughing.
In the bakery, Albert says "the Schnecken beckons". He should have said, with perfect rhyme, "the Schnecken beckon.". In Yiddish/German, Schnecken is plural. It's a sweet pastry rolled in the shape of a snail, hence the name, which in German means snail. Singular Schnecke, plural Schencken.
The evening that Val arrives home, Albert comes upstairs in a fit. While screaming "Where is he? Where's your little Chippie," Albert throws a product of the stage skit at Armand and, as a result, the candle on the table goes out. In the next shot, the candle is lit again.
Position of the wine bottle changes in Val's hand as he talks with Armand. Then after Val sets the bottle down, we see the back label in all the two-shots of Val and Armand and the front label in the one-shots of Val.
There are two very obvious cuts during the beginning flyby, which is assembled to look like one long shot from the opening over the ocean to the close up of the stage inside the club. The first is when the shot pans down to the street in front of the club. Most of the cars shift to the right and some are different. Then again as the shot approaches the front door, the action inside the door cuts to a different shot.
When Armand is calling Katherine from his car, he is supposedly leaving Miami Beach on his way to Miami. But the cruise ships in the background clearly show that he is heading east to Miami Beach *from* Miami.
When Senator Keeley is talking about his trip through the Virginia country side he refers to taking 75. 75 is either in reference to Route 75 or Interstate 75. Neither run through Virginia. Interstate 75 is the closer of the two, but runs through Kentucky. Keeley mentions driving through Virginia and Tennessee, this means he most likely took I-81, which would fit his description of Virginia pretty well.
Armand indicates that his cemetery plot is on Key Biscayne. There are no cemeteries, nor would there ever be in this highly up-scale, resort community that is an island "key." Key Biscayne is at best, a few feet above sea level precluding ever having burials on the island secondary to the water table.
Examining the books on the shelf at Armand's home, the senator's wife remarks that he has the complete set of Nancy Drew books. While the blue-bound books on the top shelf might be Nancy Drew books, there are nowhere near enough of them to complete the set. All the other books on the shelf have binding of different colors and would not be books from that series.
