Sondra Locke: a charismatic performer defined by a toxic relationship with Clint Eastwood
This covers some of her career and a bit about the legal contest.
Nobody seems to mention her first movie, The Heart Is a Lonely Hunter, which I saw long ago. She did 14 movies and some TV between 1968 and 1986. I don't even remember Planet of the Apes TV series.

Sondra Locke was an actor, producer, director and talented singer. But it was her destiny to be linked forever with Clint Eastwood, whose partner she was from the mid-1970s to the late 1980s. She was a sexy, charismatic performer with a tough, lean look who starred alongside Eastwood in hit movies like The Outlaw Josey Wales, The Gauntlet, Every Which Way But Loose (in which she sang her own songs — also for the sequel Any Which Way You Can) and Bronco Billy. But the pair became trapped in one of the most notoriously toxic relationships in Hollywood history, an ugly, messy and abusive overlap of the personal and professional — a case of love gone sour and mentorship gone terribly wrong.
Locke was already married when she met Eastwood — to a gay sculptor called Gordon Leigh Anderson, with whom she had a platonic relationship. She never divorced him and the marriage was still legal throughout her relationship with Eastwood, a fact which undoubtedly counted against her in their painful . She became a test case and talking-point in America’s sexual politics debate when she sued Eastwood twice, once for “palimony” after their relationship acrimoniously ended, and then a second time for fraud, alleging that the project-development deal Eastwood subsequently set up for her was a trick, designed to buy off the palimony suit and which resulted in no directing jobs. She claimed she had been thrown out of her house by the man she thought was the love of her life. It could well be that Locke was the victim of macho mind games, and her case was an eerie echo of the critic Pauline Kael who was suckered into (temporarily) quitting her job at the New Yorker by Warren Beatty for a similarly unproductive production deal.
