That list is long...
Pernell Roberts (Bonanza)
Valerie Harper (Valerie/The Hogan Family)
McLean Stevenson (MASH)
Shannen Doherty (Original 90210)
David Caruso (NYPD Blue)
Wayne Rogers (MASH)
Janet Hubert Whitten (the first "Aunt Viv" on Fresh Prince of Bel Air.)
And dozens more.
I think if Fawcett had demanded more money she would have got it. It was more likely she quit after one year because she wanted to show she had the acting chops for more serious roles (which she pretty much did)
Charlie's more like Suzanne Somers of Three's Company (and nothing much else), where it was about money.
Charlie? Well anyone who states their ambition is to "make movies with superstars", should probably not be relying on acting.
