When Pete is waiting for his fare (the judge) to come back to the cab for his return trip, he finally gives up on him and as he prepares to depart, he pulls up the metal flag to indicate that the cab is on duty and available. The cab stalls, and Pete gets out and opens up the hood. A few minutes later, the judge gets back in the cab, and Pete closes the hood. The metal flag is no longer up, although Pete did not put it down.

In the beginning of the movie Henry leaves her apartment wearing solid color jeans and a patch-work jacket. The jeans have seams as if they are constructed in patch fashion, but they are made with same color denim fabric. Then as the actor's body doubles ride their motorcycle to work, Henry's jeans change to a patch-work pattern to match the jacket, with the left thigh dark blue and faded blue from the knee down. But then when Streisand arrives as Henry's, the patch-work jeans have changed again, and are now constructed with faded fabric for the thighs and dark denim from the knees down to the boots.
