Mark Frechette (December 4, 1947 – September 27, 1975)
was an American film actor. He is best known for his lead role in the 1970 film Zabriskie Point, directed byMichelangelo Antonioni, in which he was cast despite having no previous acting experience.
He appeared in two other films made in Italy and Yugoslavia, Many Wars Ago (Uomini Contro, 1970) and La Grande Scrofa Nera (1971).
He tithed his $60,000 earnings from Zabriskie Point and other films to Mel Lyman's commune.
Frechette was selected from among thousands during a casting process that lasted nearly a year. He was discovered in Boston by Sally Dennison, Antonioni's assistant and casting director, while in the middle of a violent shouting match at a Charles Street bus-stop. As Antonioni toured the U.S., experiencing culture clash first hand and shooting background footage, Dennison saw Frechette, a carpenter, scream and throw a flowerpot at a woman on the street. Another version centered on Frechette getting in a verbal argument with a person who was on the third floor of an apartment building above him, which is the one referred to in many interviews. "He’s twenty and he hates," Dennison told Antonioni. The director immediately cast Frechette, a non-actor, in the films leading role: a student, wrongfully hunted for the murder of a policeman during a college uprising. Mark Frechette and Antonioni disagreed bitterly about the script during filming.
Despite the film's being a critical and box office failure, Frechette enjoyed a period of considerable publicity, his face gracing the covers of Look Magazine  in November 1969 and Rolling Stone magazine on March 7, 1970. He also notably appeared on the cover of Sight and Sound, the March 1970 and September 1970 covers of Films and Filming alongside several other magazine. He also appeared in the November 1969 issue of Vogue (magazine) in a fashion shoot. He appeared on the Merv Griffin Show alongside Abbie Hoffman when the latter controversially wore the American Flag as a shirt and Frechette got in a fight with another guest, which was later discussed during his appearance on the Dick Cavett Show in April 1970 with his Zabriskie Point co-star Daria Halprin. He and Daria were romantically involved for a time after the film and often referred to as the first counter-culture couple.
On August 29, 1973, he and two members of the Fort Hill commune attempted to rob the New England Merchant's Bank in the Fort Hill section of Roxbury, a poor neighborhood of Boston, Massachusetts. One of the members of the commune, Christopher "Herc" Thien, was killed by police and Frechette was arrested and sentenced to the minimum security state prison in Norfolk, Massachusetts. According to the Hungarian Wikipedia article on 'Zabriskie Point' the Hungarian film director in emigration, Dezso Magyar wrote the following in the March edition of the 'Filmkultura' magazine about this incident: 'To give you an example, my first friend was Mark Frechette, protagonist of the film Zabriskie Point. We wanted to make a film, to adapt a part of 'Sin and Punishment' because we felt that America was like a Dostoyevsky-type world. Mark said that he would get the money in Boston. He phoned me every second day and always assured me that he almost had the money. One day he called me and said that he would bring the 5 million dollars the next day. Great! I was watching TV in the evening when it was announced that (...) Mark Frechette attempted to rob a bank at gunpoint (...) and was arrested.' He died during an apparent weightlifting accident when a 150-pound bar fell on his neck, choking him to death. Prison officials did not suspect foul play; however, questions arose whether Frechette had been suffering from depression. He was 27 years old.
Daria Halprin (born December 30, 1948) is an American author, dancer, and former actress known primarily for her naturalistic performances in three films of the late 1960s and early 1970s.
In 1968, she appeared in Revolution, a documentary by Jack O'Connell. Shot mainly in San Francisco, the film exposed the thriving counterculture movement and featured a series of interviews with that city’s hippieresidents.
Subsequently, Halprin was chosen by Italian director Michelangelo Antonioni for the lead in his second English-language feature, Zabriskie Point. The film, released in 1970, was a statement on the burgeoning violence in America and the growing rift between the establishment and the counterculture as interpreted through a European sensibility. Following release of the film, with her Zabriskie Point co-star Mark Frechette, Halprin briefly joined self-styled guru Mel Lyman, a former member of the Jim Kweskin Jug Band, and his 100-member commune, before fleeing due to the severity of cult life.
In 1972, Halprin appeared in her third and final movie, John Flynn's thriller The Jerusalem File, in a major role alongside Nicol Williamson and Donald Pleasence. Also in 1972, she married actor/director Dennis Hopper. The marriage produced one child, Ruthanna Hopper, before the couple divorced in 1976.
In the 1970s, Halprin developed an interest in creative arts therapy. In 1978, she and her mother Anna founded the Tamalpa Institute 
and developed the Halprin Process, an expressive arts approach for transformative healing that integrates movement/dance, visual arts, performance techniques and therapeutic practices. She has authored The Expressive Body in Life, Art and Therapy, Coming Alive: The Creative Expression Method, and was a contributing author to Foundations of Expressive Arts Therapy.
