Lesley-Anne Down's character was originally going to be named Sheila, but Down explained to Aaron Spelling that Sheila is a derogatory Australian slang term for a woman and might cause problems with overseas sales. She suggested Olivia or Stephanie as alternatives, so the character became Olivia Harrow Richards.
'Kristin Davis' was originally offered the role of Meg Cummings, but she turned it down.
The character of Meg was originally named Susan Cummings, but was changed when Susan Ward was cast in the role.
Originally, Vanessa Dorman was to play Tiffany Thorne but she got the role of Kayla Richards instead (the character name Kayla was changed to Caitlin before filming began).
Clive Robertson landed the role of Ben Evans during a three-week vacation in Los Angeles. He had only a few weeks to return to his home in London, England, acquire a visa, and move to a new country.
When Susan Ward had to leave shooting of Sunset Beach to shoot 'The In Crowd (2000)', 'Tiffani Theisen' was offered to be the temporary recast of Meg Cummings. However she declined, and Meg Cummings #2 was then Sydney Penny, who played the role until Susan Ward returned.
