All You Need Is Cash (also known as The Rutles) is a 1978 television film that traces (in mockumentary style) the career of a fictitious English rock group called the Rutles. As TV Guide described it, the group's resemblance to the Beatles is "purely – and satirically – intentional".The film was co-produced by the production companies of Eric Idle and Lorne Michaels, and it was directed by Idle and Gary Weis. It was first broadcast on 22 March 1978 on NBC, earning the lowest ratings of any show on American prime time network television that week, though those who did watch it gave almost unanimously good reviews. It did much better in the ratings when it premiered in the UK on BBC2 on 27 March 1978.
