The Region 4 DVD incorrectly lists this episode as being titled "I Knew You Were a Pig".
Glenn Close (Patty Hewes) and William Hurt (Daniel Purcell) co-starred in The Big Chill (1983).
In the complete series set, the episode is listed as "I Knew Your Pig", but in the deleted scenes section it is listed as "I Knew You Were a Pig".
