The title is based on a quote by Alexander Pope, "Fools rush in where angels fear to tread."
Sole series appearances by a number of veteran stars: Michael Fox and Paul Lambert as Wentworth board directors, and Peter White as banker Ellis Newton (who earlier this season appeared twice as Bill Rockwell on rival series Dynasty (1981)).
Dennis Patrick returns as Vaughn Leland after a couple seasons' absence. Leland was last seen in Waterloo at Southfork (1981). Afton's revulsion at the sight of him in her home was because of J.R.'s coercing her into an affair with Vaughn in the fifth season.
Barbara Cason makes her sole series appearance as government bill collector Iris Porter. Porter was married to Dennis Patrick (Vaughn Leland) from 1970 until her passing in 1990.
