This episode incorporated footage of Humphrey Bogart with new footage of an impersonator, Robert Sacchi. Bogart is actually credited as a guest star in the episode. This may be the first time that a TV series has given a guest star credit to an actor who has been dead for close to 40 years.
Isabella Rossellini's monologue ("You'll have to do the thinking for both of us") is a direct spoof of lines famously delivered by her real-life mother, Ingrid Bergman.
This episode was the only episode that used computer graphics imagery. This was for "resurrecting" the long deceased Humphrey Bogart, by using old films to digitally insert his face on either a stand-in, or a dummy, in scenes where the main character's face is shown in mirrors and other reflective surfaces, since the whole episode is seen through his point of view. The effects were done by Industrial Light & Magic, which also previously worked on Robert Zemeckis' Oscar winning film Forrest Gump (1994).
This was the last episode to have been filmed on American soil. Season 7 saw production moved to the United Kingdom.
