Oscar-nominee and Clint Eastwood’s ex, actress Sondra Locke, has passed away aged 74 from cardiac arrest that was a result of breast and bone cancer.

Locke was nominated for her Academy Award for her debut role in 1968's The Heart is a Lonely Hunter alongside Alan Arkin.

Perhaps her most famous roles were in the six films she did with her romantic partner Clint Eastwood. Eastwood and Locke became romantically involved on the set of 1976's The Outlaw Josey Wales. After this, she almost exclusively acted in Eastwood films for some time, next appearing in 1977's The Gauntlet, 1978's Every Which Way But Loose, Bronco Billy and Any Which Way You Can in 1980, and 1983's Sudden Impact.

Locke said that Eastwood asked her to appear exclusively in his films during that time, which she did because "I was in love… and I loved working with him." 

That love was apparently gone by 1989 when Locke filed a palimony lawsuit against Eastwood. The suit included a 3 year $1.5 million contract for her to work and direct at Warner Bros. She had also begun chemotherapy for her cancer and had undergone a double mastectomy by this time.

The studio ended up not green-lighting any of Locke's 30 pitches to them and the deal created a "dead end for her career" according to her lawyer. Locke came to the conclusion that Eastwood had secretly financed the "bogus" deal and sued him again in 1995 for fraud, this time taking a $2.5 million settlement.

Even though acrimony characterized her relationship with Clint Eastwood, Sondra Locke will undoubtedly best be remembered for her roles with him and her debut. See some relevant trailers from her career below.
