At the time this movie was being filmed, the demolition of the above-track-level portions of New York's Pennsylvania Station was beginning. In the opening scene of Evie Jackson's arrival in New York, you can see several panes of station windows broken and replaced with boards. By 1966, the station had been converted from its old to its new form, and the new Madison Square Garden had been added on top of it.
Both Sandra Gould and Alice Pearce appear in this movie, the original and replacement Gladys Kravitz characters from the magical sitcom 'Bewitched (1964)'.
