"Holsten's in Bloomfield, New Jersey, [where the infamous final scene of the series takes place and which also appears in the film] hadn't really changed much over time. The owners had some historic photographs that we could reference. But the frustrating thing there was that there are buildings across the street that needed almost no work for the period but, if you're looking out from Holsten's, they were a little bit left so you couldn't really see them directly out the window."
