Cracked Actor is a 53-minute-long BBC television documentary film about the pop star David Bowie. It was filmed in 1974. At the time he was a cocaine addict and the documentary has become notorious for showing Bowie's fragile mental state during this period. It was made by Alan Yentob for the BBC's Omnibus documentary strand, and was first shown, on BBC2 in the United Kingdom, on 26 January 1975. The documentary depicts Bowie on tour in Los Angeles, using a mixture of documentary sequences filmed in limousines and hotels, and concert footage. Most of the concert footage was taken from a show at the Los Angeles Universal Amphitheatre on 2 September 1974. There were also excerpts from D.A. Pennebaker's concert film Ziggy Stardust and the Spiders from Mars, which had been shot at London's Hammersmith Odeon on 3 July 1973, as well as a few other performances from the tour. Cracked Actor is notable for being a source for footage of Bowie's ambitious Diamond Dogs tour.
