Background: LaBeouf was born in Los Angeles, California, as the only child of Shayna (nee Saide) and Jeffrey Craig LaBeouf. His mother is a dancer and ballerina turned visual artist and clothing jewelry designer. His father is a Vietnam War veteran who had numerous jobs. LaBeouf's mother is Jewish, and his father, who is of Cajun descent, is Christian.
Context: In early 2014, LaBeouf began collaborating with British artist and author of The Metamodernist Manifesto, Luke Turner, and Finnish artist Nastja Sade Ronkko, embarking on a series of actions described by Dazed as "a multi-platform meditation on celebrity and vulnerability". Since then, LaBeouf, Ronkko & Turner have engaged in numerous high-profile performance art projects, including #IAMSORRY (2014), #ALLMYMOVIES (2015), #TOUCHMYSOUL (2015), #TAKEMEANYWHERE (2016), and HEWILLNOTDIVIDE.US (2017-ongoing).  On February 9, 2014, the artists caused controversy at the Berlin Film Festival when LaBeouf arrived at the red carpet wearing a brown paper bag over his head with the words "I AM NOT FAMOUS ANYMORE" written on it. In a conversation conducted as part of the trio's #INTERVIEW piece in November 2014, LaBeouf said that he was "heartbroken" and "genuinely remorseful and full of shame and guilt" at the start of their subsequent #IAMSORRY performance, in which he occupied a Los Angeles gallery for six days wearing the paper bag and silently crying in front of visitors, but that "in the end I felt cared for however it came--it was beautiful, it blew me away." He revealed, however, that one woman had proceeded to sexually assault him during the February performance, while Ronkko and Turner later clarified that they had prevented the assault by intervening as soon as they were aware of the incident starting to occur.  In 2015, LaBeouf appeared in #INTRODUCTIONS, a half-hour video made by LaBeouf, Ronkko & Turner in collaboration with Central Saint Martins Fine Art students, comprising a series of short monologues performed by LaBeouf in front of a green screen. One segment in the form of an exaggerated motivational speech, dubbed "Just Do It" after the Nike slogan, became an Internet meme after going viral within days of being released, spawning numerous remixes and parodies, and becoming the most searched for GIF of 2015 according to Google.
Question: Why did he colaborate with them?
Answer: embarking on a series of actions described by Dazed as "a multi-platform meditation on celebrity and vulnerability".

Problem: Background: Cimino was born in New York City on February 3, 1939. A third-generation Italian-American, Cimino and his brothers grew up with their parents in Old Westbury, Long Island. He was regarded as a prodigy at the private schools his parents sent him to, but rebelled as an adolescent by consorting with delinquents, getting into fights, and coming home drunk. Of this time, Cimino described himself as "always hanging around with kids my parents didn't approve of.
Context: Interviews with Cimino were rare; he declined all interviews with American journalists for 10 years following Heaven's Gate and he gave his part in the making of that film little discussion. George Hickenlooper's book Reel Conversations and Peter Biskind's highly critical book Easy Riders, Raging Bulls deal with the film and resulting scandal. Hickenlooper's book includes one of the few candid discussions with Cimino; Biskind focuses on events during and after the production as a later backdrop for the sweeping changes made to Hollywood and the movie brat generation. Steven Bach, a former UA studio executive, wrote Final Cut (1985), which describes in detail how Heaven's Gate brought down United Artists. Cimino called Bach's book a "work of fiction" by a "degenerate who never even came on the set". However, Bach's work does discuss times in which he did appear at the shooting location to confront Cimino about the budgetary issues.  While Al Pacino, Meryl Streep, Francis Ford Coppola, Gene Hackman, Sidney Lumet and Robert De Niro all gave interviews for the 2009 John Cazale documentary I Knew It Was You, Cimino refused to do so.  However, the European DVD release of The Deer Hunter contains an audio commentary with Cimino as does the American DVD release of Year of the Dragon.  In 2011, the French movie critic Jean-Baptiste Thoret wrote a large profile on Michael Cimino for Les Cahiers du Cinema. Cimino appeared on the cover.  In 2013, Thoret published in France an acclaimed book, Michael Cimino, les voix perdues de l'Amerique (lost voices of America). Flammarion. ISBN 978-2081261600
Question: Is there any more information about his interviews?
Answer:
However, the European DVD release of The Deer Hunter contains an audio commentary with Cimino as does the American DVD release of Year of the Dragon.
