As of 2020, this is the most recent television episode in the shared universe that also includes the Mission: Impossible franchise, Mannix, Matlock, Jake and the Fatman, Diagnosis: Murder, and Touched by an Angel spin-off Promised Land. Diagnosis: Murder originated from a 1991 episode of Jake and the Fatman, in turn inspired by a two-part 1986 episode of Matlock, whose title character later appeared on Diagnosis: Murder in 1997. The latter show had guest appearances from characters on M:I and Mannix, and had a two-part crossover with Promised Land, linking all these shows and movies as part of one shared universe, which continues to produce films as part of the Mission: Impossible franchise on a consistent basis. The entire shared universe is owned by ViacomCBS.
