'' Katherine '' ( also known as '' The Radical '' ) is a 1975 American made-for-television drama film written and directed by Jeremy Kagan , and starring Sissy Spacek , Art Carney and Henry Winkler . Intended to portray the time period of the Vietnam War , the title character was loosely based on Diana Oughton of the Weather Underground , who died in the 1970 Greenwich Village townhouse explosion when a bomb she was building accidentally exploded . Reviewers have also noted that '' Katherine '' also " borrowed from the then-current headlines involving Patty Hearst , another heiress whose exact level of voluntary involvement with the Symbionese Liberation Army remained hazy in 1975
