Hal Ashby's ex-wife question.
Wikipedia:
In 1970 he married actress Joan Marshall, today probably best known for her guest appearance in the Star Trek episode "Court Martial" as antagonistic prosecutor Arleen Shaw. While they remained married until his death in 1988, the two had separated by the mid-seventies, with Marshall never forgiving her husband, Warren Beatty, and Robert Towne for dramatizing certain unflattering elements of her life in Shampoo.
Anybody know anything about these unflattering elements?
