Who Killed the KLF? is a 2021 documentary film by Chris Atkins about The KLF.The unauthorised documentary includes reconstructions of the band's dramatic gestures, played by actors. KLF members Jimmy Cauty and Bill Drummond refused to take part in the film or to authorise it. However, old interviews with them, recorded on audio cassettes, were used. Limited clips of their music were included under the fair dealing copyright exception. The KLF originally sought to block the film's release due to alleged copyright infringement, but later approved of the film.
