This is the second time Dale Robertson has starred, but has been uncredited in the cast list, the previous one being The Last Flight of the Dixie Damsel (1988)l.
The final restaurant scene with Dale Robertson and Angela Lansbury was filmed in the Universal Studios VIP commissary dining room prior to the studio's renovation of the room in 1990. The booth they occupy was always reserved for Lew Wasserman.
The auto crash sequence was filmed in miniature. The auto was a 'duplicate of the Chrysler hero car' - a miniature toy available at the time of filming.
The ranch house exteriors, interiors, and stables were filmed on location in Hidden Hills. The rear patio area behind the foyer hallway staircase, including the the patio area behind the living room séance scene, were tented (black duvyteen tarp) for the film's night sequence, which were filmed during the day.
The title is a variation of Prescription: Murder (1968), written by Richard Levinson and William Link who co-created Murder, She Wrote (1984).
