John Hillerman (as Victor Sutter) uses the same assumed British accent that he (as Higgins) used during Magnum, P.I. that he learned early in his acting career.
A number of the sets are clearly from The Love Boat and in the opening scene as the burglar looks over the rail the name Pacific Princess can be seen on the side of the ship. Both shows were produced by Aaron Spelling. John Hillerman also appeared in 3 episodes of The Love Boat.
