The film's initial budget of approximately £200,000 was raised by convincing 10 separate investors to contribute £20,000 apiece. Three of those investors were the rock bands Pink Floyd, Led Zeppelin and Genesis, who were persuaded to help fund the film by Tony Stratton-Smith, head of Charisma Records (the record label that released Python's early comedy albums). According to Terry Gilliam, the Pythons turned to rock stars like Pink Floyd, Led Zeppelin and Elton John for finance as the studios refused to fund the film and rock stars saw it as "a good tax write-off" due to UK income tax being "as high as 90%" at the time.
