In 1975, Susan Dey and Michael Brandon starred in the TV movie Cage Without a Key. She played the hapless victim and he played the lawyer who tirelessly works to free her after a wrongful conviction.
Several years later, Susan Dey and Michael Brandon worked together again...sort of. In 1983, Susan Dey had joined the core cast of the short-lived prime time soap Emerald Point N.A.S. Halfway through the show's one season run, Michael Brandon began appearing on the series. However, Michael Brandon's character was tied-in with another character on the show, so the pair did not get to share the screen all that much.
