Goof: When explaining the set-up for the Moldavian wedding massacre, Gordon Thomson confuses the 1987 season-ending cliffhanger with the 1985 season-ending cliffhanger (Moldavian wedding massacre) by explaining that Bo Hopkins (Matthew Blaisdel) had returned to the show to disrupt the wedding. The Moldavian wedding massacre occurred at the end of the 1984-1985 season, while Bo Hopkins did not return to the show until the end of the 1986-1987 season, which featured the wedding of Adam and Dana.
The reunion features the first on-screen appearances of Pamela Sue Martin (Fallon) and Catherine Oxenberg (Amanda) together, as well as Al Corley (Steven) and Gordon Thomson (Adam) together. In the series, Fallon and Amanda were only seen on-screen together once during a 7th season episode. However, they were both played by the second actresses to play each role (Emma Samms and Karen Cellini) and not Martin and Oxenberg.
Additionally, the character of Adam (played by Gordon Thomson) did not appear until after Al Corley left the show. When Steven was reintroduced on the series, he was played by Jack Coleman who played opposite on-screen brother Thomson for 6 seasons. In the 1991 mini-series, Corley did reprise the role of Steven, however, Adam was now played by Robin Sachs.
The reunion was filmed at the Filoli Estate in Woodside, California, near San Francisco, where the pilot was filmed. Exteriors of the Filoli estate were used in the opening credits and through-out the series.
In this episode, Blake and Krystle renew their wedding vows. This episode aired exactly 8 years to the date of the pilot episode of Dynasty, in which Blake and Krystle wed the first time.
In the morgue, the second time they show a close up of the "corpse" his eyelids move quite noticably.
When Krystal is diagnosed with this "mystery" illness that turns out to be brain damage, Blake gets solemn and thinks back to her being thrown from and dragged by the horse many years before (the episode that caused her miscarriage). This is claimed to be when the doctor told them she might suffer head trauma, but this never happened. It was actually when Blake & Krystal were run off the road in their car by the man who's wife had been killed in the La Mirage fire that this later doctor made the prognosis.
