Madlyn Soloman Rhue (née Madeline Roche, October 3, 1935 – December 16, 2003) was an American film and television actress.
Rhue was diagnosed with multiple sclerosis, but she continued to work, including a role in Days of Our Lives as Daphne DiMera; but by 1985, she needed a wheelchair and was limited to roles that did not require her to walk or stand, such as recurring roles in Murder, She Wrote and Houston Knights. Angela Lansbury created a role for her when she heard that Rhue was at risk of losing her insurance because she could no longer work enough hours. Her illness prevented her from reprising her Star Trek role as Lieutenant Marla McGivers in the film Star Trek II: The Wrath of Khan (1982), and the character was ultimately written out of the script as director Nicholas Meyer did not wish to re-cast the part.
She eventually became completely incapacitated by multiple sclerosis and died from pneumonia at the age of 68 at the Motion Picture & Television Country House and Hospital in Woodland Hills in Los Angeles, California.
