Jo Heims

By 1974, Heims had composed a script for a horror-suspense film titled "Mrs. Manning's Weekend". It was purchased by director-producer Peter S. Traynor, then rewritten and released as Death Game three years later. She then completed the women in prison teleplay Nightmare in Badham County, a television movie. Not long after, Heims fell ill with a breast cancer diagnosis. Her final work was another TV feature, the murder mystery Secrets of Three Hungry Wives. Heims wrote the teleplay as long as she could before handing it off to executive producer Alan Surgal to finish. Heims died on April 22, 1978 in Los Angeles at the age of 48. Eastwood reportedly attended her funeral.

Heims married William Duffy in August 1972. That same year, Universal distributed the thriller You'll Like My Mother, a script that Heims adapted from a novel by Naomi A. Hintze. The following year, she collaborated with Eastwood again by writing Breezy, also distributed by Universal. The drama depicts a romance between a jaded, middle-aged divorcee and a much younger, free-spirited woman. Heims additionally served as an associate producer for the movie, allowing her to coordinate some of its creative elements. She developed the male lead with Eastwood in mind to play the part. However, the two agreed he was too young for the role, so it went to the older William Holden instead. Eastwood's then-mistress Jo Ann Harris was a strong contender for the female lead, but Heims felt Harris was wrong for the part and suggested her friend Sondra Locke. Locke was five years older than Harris and 12 years older than the character as written. Heims set up the very first meeting between Locke and Eastwood, but Kay Lenz ultimately earned the part as Locke was too old to be credible in it.

While working at Universal Pictures, Heims crossed paths with and befriended Clint Eastwood, then an up-and-coming actor. By the late 1960s, Eastwood had achieved international fame as a western-action star and began directing his own films. Heims drafted a 60-page screenplay for Play Misty for Me, a psychological thriller that would soon become Eastwood's directorial debut. The plot follows a radio disc jockey who becomes a stalking victim of an obsessed, female fan. Heims based the latter character on a woman she knew after it was suggested to her by an acquaintance. Although he initially optioned the script, Eastwood encouraged Heims to sell it to Universal when she received a larger offer. The company shelved the project, so when Eastwood later signed a three-picture contract with Universal, he regained the screenplay and had it revised by Dean Riesner. Play Misty for Me was released in 1971, the year Eastwood also took the title role in the crime thriller Dirty Harry. Heims contributed to the story of the latter film, but she received no screen credit.
