Even though the plot centers around three roommates, the three cast members didn’t actually meet until the night of the first taping. This was partly because Suzanne Somers was such a last-minute addition to the cast.
But the three actors proved their talents by creating collective, on-screen chemistry for the show.
Jack Tripper Got His Own Spin-off.
After the end of "Three's Company," there was yet another spin-off attempt by the producers of the show. ABC then attempted to launch the show, "Three's a Crowd."
The plot centered around Jack Tripper moving in with his new girlfriend but (maybe because it was too similar to "Three’s Company") this spin-off fizzled out as well.
Priscilla Barnes Got In Trouble For Her Hair Being “Too Blonde.”
Producers really struggled to find a replacement for Somer’s character. After the departure of Chrissy, she was replaced by Cindy, and after Cindy was written out of the show, she was replaced by Terri (played by Priscilla Barnes).
According to Barnes, she said the producers didn’t want her because her hair was dyed “too blonde”. What’s a girl to do?
Jack Tripper is The Only Character to Appear in Every Episode.
Even though the show had three stars, John Ritter was clearly number one (for both the writers and the producers apparently).
His character, Jack, was the only one to appear in every episode of the show. That might explain his big salary!
Don Knotts Was Nervous When He Got Hired
After the departure of the Ropers, Jack, Chrissy, and Janet needed a new landlord, that’s when actor Don Knotts was cast. Surprisingly, though Knotts was a veteran of TV, he said that he was nervous at first because the show was already so popular and the cast so funny.
On the other side, many cast members confessed they were nervous to work with an actor as seasoned as Knotts.
