When Noland shows Patty the new model house, the sign out front says "Castle Heights Tract Homes". Castle Heights is an actual Los Angeles neighborhood where such homes were being built at the time. It is situated between Chevoit Hills, Beverlywood and the Santa Monica Freeway.
The cast is full of actors who would later become stars or regulars on hit TV series. Carolyn Jones is best known as Morticia on The Addams Family (1964). Claude Akins was Sheriff Lobo on both B.J. and the Bear (1978) and The Misadventures of Sheriff Lobo (1979). William Schallert was the dad on The Patty Duke Show (1963). For 30 years John Beradino was Dr. Steve Hardy on General Hospital (1963). Richard Deacon was the stuffy producer Mel Cooley on The Dick Van Dyke Show (1961). And Stafford Repp was Police Chief O'Hara on Batman (1966).
The $25,000 Noland steals from the bookie would be the equivalent of about $255,000 in 2021.
The model home Barney shows Patty was in a real housing development under construction at the time. In 2021 that home's estimated value was $1.7M.
