 Since late 1969, Led Zeppelin had been planning on filming one of their live performances for a projected movie documentary of the band.The group's manager, Peter Grant, believed that they would be better served by the big screen than by television, because he regarded the sound quality of the latter as unsatisfactory.The first attempt was the filming (by Peter Whitehead and Stanley Dorfman) of Led Zeppelin's Royal Albert Hall performance on 9 January 1970, but the band thought they appeared dated when they viewed the edited footage several months later, and the film was shelved (this footage was later remastered and featured on the 2003 release "Led Zeppelin DVD").
