Ron Foster used to play Matthew's right hand man. Now William Boyett plays that part and Foster appears here as unnamed plain clothes Detective. Obviously had a promotion.
The getaway car Myra Davis drives, is a gray over green 1958 Plymouth Belvedere 4 door Sedan. Myra Davis later drives a light colored 1958 Pontiac Chieftain 4 door Sedan. Visible on the billboards are "PontiacChieftain." Also visible is "Pontiac" on the hood and trunk lid. This is one of the few, if any times in the series that a "Pontiac" was used. Sergeant Garvey #2738 is driving a dark colored 1958 Buick Super Riviera 4 door Sedan-Model 53.
All three supporting officers, (Actors William Boyett, Vance Skarstedt and Ron Foster) are either wearing a Sergeant's Uniform or referred to as a sergeant (Foster) in this episode.
