While Chris is searching for files in Belasco's home, she comes across a painting of a man with a sinister smile. This painting was previously featured in a 1971 Night Gallery segment titled, "With Apologies to Mr. Hyde", starring Adam West.
John Carradine, who portrays retired horror movie actor Loren Belasco, previously played Count Dracula in House of Frankenstein (1944), House of Dracula (1945) (scenes from both of which are seen on Chris' TV screen in this story), as well as in Dracula (1956), Billy the Kid Versus Dracula (1966) and would do so again in Nocturna (1979).
Ken Lynch played the role of Grover once more in another show written by Glen A. Larson: The Night the Cylons Landed: Part II (1980). However, here Grover is a uniformed cop rather than a plainclothes detective. An early version of the Galactica 1980 script featured even more direct references to McCloud. It included the character of Police Chief Peter B. Clifford who at one point mentions McCloud by name. These references were omitted when actor J.D. Cannon was unable to appear. Ironically, actor Peter Mark Richman, who played Clifford in the pilot movie for McCloud, appears in both parts of this Galactica story as Colonel Briggs.
