When Elizabeth and Philip are in the bar, he orders two Millers but is later shown drinking a Miller Lite.
Philip pulls Elizabeth's lower tooth, but it comes out with the roots face up (as an upper tooth would.)
Philip pulls Elizabeth's tooth in two parts with an ordinary household plier -- once the top of the tooth broke off, there would be no way to pull the root out with such a blunt plier.
While various CIA agents are tailing Elizabeth's car, a closeup of a modern LED traffic light is shown. This episode takes place in 1982. LED traffic lights weren't introduced in the US until the late 1990s.
