Al Corley, who took the controversial role of Steven Carrington in order to exploit the social impact of playing the first openly gay main character in a prime-time series, quit when the show's producers caved into network demands that Steven Carrington be cured of his homosexuality. Jack Coleman was hired to replace Corley and in order to explain away the change in actors, a storyline was written where Steven was in an oil rig explosion that required extensive plastic surgery to fix, resulting in Steven being given a brand new face as a result of numerous surgeries to rebuild his face.
When Alexis was introduced for the cliff-hanger finale of season one, the character had not yet been cast. Joan Collins was cast during the break between season one and two. In the season one cliff-hanger, Alexis was introduced during a trial as a surprise witness to testify against Blake. A friend of the producers played the part of the yet-uncast Alexis, who made a dramatic entrance wearing dark glasses and a wide-brimmed hat with a veil covering most of her face.
The original plans for the second part of season 7 was that Blake would develop amnesia and fall in love with Alexis. However, this was changed because John Forsythe routinely vetoed any storyline involving adultery.
Heather Locklear was a regular in season two, and left to join another Aaron Spelling program, T.J. Hooker (1982), but continued to make appearances on "Dynasty". She rejoined the series as a regular in season six.
Despite popular belief that Alexis Carrington was designed as a rip-off of JR Ewing of Dallas (1978), the character was originally conceived as being a low key passive-aggressive villainess. Joan Collins, who was a fan of Dallas (1978) and the JR Ewing character, suggested that the writers portray Alexis as an all-out female version of JR Ewing. Collins' suggestion was backed by ABC executives, who felt that "Dynasty" needed a JR-type character to go head-to-head with Dallas (1978).
Except when famous jewellers such as Tiffany, Harry Winston or Edwar of Beverly Hills lent their jewelry to the actresses, the jewelry was created by Nolan Miller who also designed all the clothes for the show. To the shock of many fans, Miller admitted that all of the jewelry he created was fake.
This was the very last acting role for Rock Hudson' who played Daniel Reese from December 1984 to April 1985. (Hudson's last appearance as "himself" was with longtime pal Doris Day on the premiere episode of her series Doris Day's Best Friends (1985).) Hudson passed away of AIDS on October 2, 1985. Incredibly, so little was known about AIDS at the time of this series that it was thought to be transmissible by casual contact, and many feared for the health of Linda Evans because she had kissed Rock Hudson in a scene on the show. Even more incredibly, a minor panic broke out in Hollywood about kissing scenes in films and TV. The "National Enquirer" gossip tabloid carried a picture of Rock Hudson kissing Linda Evans', and carried a story which further fueled the rampant paranoia at the time.
Diahann Carroll had planned to make some cameos during the show's eighth season, but it never happened because of budget problems. It was also rumored that she would have rejoined the cast during the tenth season, but "Dynasty" was taken off the air after the ninth season.
The original plans after the infamous Moldavian Massacre were for King Galen to propose Alexis to marry him and become Queen of Moldavia. Alexis would have refused the proposal, however a dream sequence of the wedding had been shot in December 1985. Because the viewer response to the entire Moldavian storyline was highly unfavorable, several scenes of three episodes were replaced by new scenes, including the royal wedding dream sequence.
Al Corley quit the series because his character, Stephen, kept flip flopping; one season he was gay, the next season he was "giving up the lifestyle" according to the character, and back and forth and back and forth again. He felt that was sending out a mixed message to the audience and not being true to what the character was.
Producers tried to conceal Pamela Bellwood's real-life pregnancy in season 6 as it was not written into the script, but it was sometimes apparent on-screen that she was pregnant. Pamela also missed five episodes in mid season 6 when she had her baby.
One area where the series was the undisputed champ against Dallas (1978) was fashion. While Dallas had common, undistinguished clothing for its characters, Dynasty fashion was so popular and influential on television, it started its own industry. Both Linda Evans and Joan Collins started their own popular fashion lines, and magazine covers across the country celebrated Dynasty fashion. Dynasty, with its glammed up powersuits and shoulder pads, redefined fashion for the eighties.
In an "Archive of American Television" interview, John Forsythe said that the first couple of seasons were good. He said they were relevant and they had "punch". He said by the last season, though, most of the shows were bad.
Costume designer Nolan Miller designed approximately 3,000 costumes over the course of the series, saying "I never want to see them wearing the same outfit twice". His weekly wardrobe budget was $35,000.
