Jill Donohue had appeared earlier in January of 1968 with Doug McClure in the episode With Help from Ulysses of the Virginian TV series. Both the movie Nobody's Perfect and The Virginian were produced that same year by Universal.
Nancy Kwan and James Shigeta starred together in "Flower Drum Song" (1961).
The fictitious submarine rescue ship is USS Bustard (ASR-9). The actual ASR-9 was USS Florikan, which was in service from 1943 to 1991.
