The Colbys (originally titled Dynasty II: The Colbys) is an American prime time soap opera that originally aired on ABC from November 20, 1985, to March 26, 1987. Created by Richard and Esther Shapiro and Eileen and Robert Pollock and produced by Aaron Spelling, it is a spin-off of Dynasty and revolves around the Colbys, another vastly wealthy family who own a large multinational conglomerate and are connected to the Carringtons of Dynasty. Intended to surpass its predecessor in opulence, the series' producers were handed an immensely high budget for the era, and cast a handful of well-known movie stars among its leads.

The Colbys stars Charlton Heston as tycoon Jason Colby, Barbara Stanwyck as his sister Constance, Stephanie Beacham as his wife Sable, Katharine Ross as Sable's sister and Jason's lover Francesca, and Ricardo Montalbán as Jason's business rival Zach Powers. John James and Emma Samms also star as their Dynasty characters Jeff Colby and Fallon Carrington. The Colbys was ultimately a ratings disappointment, and was cancelled after two seasons.
