Main Characters and Cast
The sitcom Three's Company features three primary characters sharing a Santa Monica apartment: Jack Tripper, played by John Ritter, and the two female roommates Janet Wood and Chrissy Snow, portrayed by Joyce DeWitt and Suzanne Somers respectively. The show centers on Jack, a culinary student who pretends to be gay to live with the women due to a strict landlord rule. John Ritter anchored the ensemble with physical comedy and improvisation. The cast defined the show's comedic tone across eight seasons.
Suzanne Somers left the series in 1984 after contract negotiations, and her character Chrissy was replaced by Cindy Snow, played by Jenilee Harrison. Later, Terri Alden, portrayed by Priscilla Barnes, joined as a permanent roommate. The core dynamic remained Jack navigating misunderstandings with Janet and the rotating female roommate while landlord Ralph Furley, played by Don Knotts, enforced the no-opposite-sex rule.

The central premise relies on Jack's secret, which fuels most episodes. Landlord Mr. Roper, played by Norman Fell, and later his wife Mrs. Roper, portrayed by Audra Lindley, serve as primary antagonists. After the Ropers move to a condominium, Don Knotts joins as Ralph Furley, whose brother Bart, played by Richard Kline, appears in multiple episodes.
