Other mistake: In the beginning of the movie, the radio announcer says it is 74 degrees with a high of 89 degrees expected. The guy directing the oil truck breath is visible and is wearing a winter coat, not very likely at that temperature. People walking the streets are too heavily dressed also.
Other mistake: In the restaurant scene with Scylla (Doc), Babe and Elsa, Scylla pontificates, briefly, about wine and then orders a Chablis Grand Cru (which you don't need to be a wine buff to know is a classic white wine). However, the wine they are drinking, a few minutes later, is a red.
