First crossover from Dynasty, by John Forsythe as Blake Carrington.
First of four appearances in the series - and one on Dynasty (1981) - by Ray Stricklyn playing psychiatrist Jimmy Lee Parris.
John James was 29 when he starred in The Colbys (1985). Katharine Ross, playing his mother Francesca, was 45, making her character quite a young mother.
Aside from flashbacks in the main show Dynasty (1981), this is the first time John James and Emma Samms share a scene in the present day.
