She went on to appear in several TV series, including "The Untouchables" and "My Favorite Martian."
Ironically, at age 15 she guest-starred in "Bachelor Father," which starred John Forsythe. Two decades later she would play Forsythe's wife in "Dynasty."
Forsythe said that when he first met Linda, "She was magnificent and very skinny. When she came to play my wife [in "Dynasty"], I said, 'Linda Evans, my, have you grown! You've blossomed in the right places."
Before landing the role of Audra, Linda changed her name from Evanstad to Evans and dyed her dark hair blonde.
Interviewed by Larry King, she said that she read for a movie part and was told by the director it was "worst reading I've seen...but you've got a quality we really like...and we'd like you to test for a TV pilot," which was "The Big Valley." She tested with Lee Majors, vying for the role of Heath, and of course, both actors got their parts.
After the four-year run of "The Big Valley," Linda later appeared in Playboy magazine, at the urging of her husband, John Derek.
In 1981 at age 39 she gained fame as oil millionaire wife Krystle Carrington in the 1980s nighttime soap "Dynasty."
"I personally was thrilled that we [herself and co-star Joan Collins] were two older women at that time to be over forty and to have a television series was shocking," she told King. "To be older and to be given these parts was just miraculous."
