The Only Actors Still Alive From The Cast Of Three's Company

Richard Kline, who played Larry, has continued to work steadily for much of his 50-plus year career, largely having returned to live theater in recent years. He's also been featured in a recurring role as Judge Angioli on "Blue Bloods" and in single-episode stints on both "Harlem" and "The Resident."
Priscilla Barnes, who played Terri in the last three seasons, used her newfound visibility from the show to get bigger roles, joining the Bond Girl ranks in "License To Kill." She also had a notable appearance in Kevin Smith's cult classic "Mallrats,” and most recently had a recurring role across all five seasons of the CW's "Jane the Virgin.”
Actress Jenilee Harrison played Cindy for only two seasons on "Three's Company." She went on to join the cast of "Dallas," but it didn't prove to be much of a career boost, and she seemingly retired from acting in the early 2000s.
Joyce DeWitt played Janet throughout the show's entire run, which is not bad for a performer who only had two minor roles before "Three's Company." DeWitt mostly played bit parts on television for the remainder of the '80s and '90s, but has worked steadily in film and on stage for the last twenty years.
The show made Suzanne Somers a household name, but in 1980, she was fired after asking to be paid the same as her male co-stars. Returning to sitcoms in the ‘90s with "Step by Step," Somers still dabbles in acting, but most of her recent appearances have been in reality and talk shows.
