Aldis Sondra Locke, who was best known for creating six films by Clint Eastwood, died at the age of 74 years.
She won the Oscar nomination for her first film, "The Heart is a Lone Hunter" in 1968.
Locke became romantically involved with Eastwood, while performing Outlaw Josey Wales in 1975, but later continued to sue him for deception when they broke.
She died on November 3 after a heart attack that was associated with her breast and bone cancer diagnosis.
When she was related to Eastwood, she filmed only with Warner Bros, including The Gauntlet (1977), Every Road, But Free (1978), Bronco Billy (1980) and Any Way You Can (1980).
Tennessee-born actress also featured in the 1983 movie "The Shock Blow", the fourth Dirty Harry series.
The couple were together for 14 years, but in April 1989, Locke filed a lawsuit against Eastwood.
During her billing, she received a contracted $ 1.5 million (£ 1.2 million) three-year contract for Warner Bros, but the studio did not accept any of the 30 projects he released.
Believing that this was Clintwood's work, she was again sued in 1995 for fraud, and eventually reached $ 2.5 million over the course of a year.
"I do not have to worry about work," she said after making settlements.
She said that the lawsuit "was never for money, it was about my struggle for my professional rights".
