During the pool scene the keys are visible in Dosmo's hand before they are thrown to him.
After the "Good Samaritan" pockets Allan's wallet and drives him away, and the owner of the car he's stolen runs out, Allan's wallet is seen lying on the street.
After Dosmo rips his body armor and extracts the bullet, he gets up and as he's getting up, the body armor is not ripped and the bullet is still in place.
Lee Woods, using his stopwatch, gives Roy Foxx 1 minute to answer 3 questions. The "minute" lasts 1 minute and 35 seconds.
Lee drives for quite awhile to reach Becky's house from the motel, but after Becky shoots Helga at the motel, Helga arrives at Becky's house by walking shot.
In the cemetery, when Audrey (Marsha Mason) and Teddy (Paul Mazurky) meet, Audrey visits a grave where the gravestone is of the Civil War-Spanish American War type, not used after 1922.
It makes no sense for Woods to pressure Foxx into confirming that Helga was his North Korean contact at gun point like that. He would of course say whatever he thought Woods wanted to hear just to save his life.
