'Kurt & Courtney' (1998)
Perhaps the most infamous film to feature Cobain, this absolutely unauthorized profile was the first work to plant the controversial seed that Courtney Love was in same way responsible for Cobain's death. Directed by notable documentarian Nick Broomfield (Aileen: Life and Death of a Serial Killer), Kurt & Courtney investigates the tumultuous relationship between Nirvana's singer and the Hole frontwoman. Although the filmmaker himself believes Cobain committed suicide, he still offers up insane interviews with odd characters like El Duce, a local punk rocker who claims Love offered him $50,000 to kill her husband.
Thanks to the efforts of Love's legal team, the doc never received a widespread release – a Sundance Film Festival premiere in 1998 was similarly nixed over threat of a lawsuit – but the documentary still inspired a nation of conspiracy theorists to flood YouTube with their own "Kurt was murdered" videos.
