A pilot for a series called Byrd's Nest was written with the same premise as Robin's Nest, with a young man living with his older girlfriend and her disapproving father, who owns the building in which they live. The series was planned as a spin-off from Three's Company and possibly a vehicle for Richard Kline, but ABC passed on the idea. As Three's Company entered its eighth season in September 1983, ratings took a dive in the face of stiff competition from the new NBC series The A-Team, and ABC approved the development of a new series to be called Three's a Crowd, starring Ritter. Development and casting of the new series occurred in secret as Three's Companys eighth season progressed. Ritter's cast members Richard Kline, Joyce DeWitt, Priscilla Barnes and Don Knotts were kept out of the loop. During a Christmas hiatus in late 1983, producers auditioned several female leads to play Jack's new love interest Vicky Bradford, and eventually decided upon Broadway actress Mary Cadorette. An embarrassing situation arose when DeWitt accidentally walked in on the auditions after visiting the studio to set up her dressing room at the end of the hiatus. Informed of the spin-off project and the looming cancellation of Three's Company, DeWitt was upset by the secrecy but soon reconciled with Ritter. She and Barnes found it difficult to tape the rest of the season, as both actresses learned that their characters would conclude with the series finale. Kline and Knotts were offered recurring roles on Three's a Crowd, but both declined the offer (Kline would make a guest appearance on the show in early 1985). Suzanne Somers reportedly lobbied to reprise her Three's Company character Chrissy Snow as Jack's love interest in the spin-off. Transition In transitioning from Three's Company to Three's a Crowd, series producers decided to follow the plot line of the British series. Season 8 of Three's Company drew to a close in a three-episode story arc. In the first of the three episodes, Janet meets wealthy art collector Phillip Dawson. In the second episode, she falls in love with him, while Jack meets and falls in love with stewardess Vicky Bradford. Her wealthy father, played by Robert Mandan, does not approve of the relationship. When first aired, the episode ended with the words "To be continued... next fall", and when rerun late in the summer, this was changed to
