Still surprisingly effective, and the template for its far more popular and successful successor, "This is Spinal Tap", "All You Need is Cash" is its own magical mystery tour... a bizarre journey through the Beatles' story that twists & turns between the inspired and the downright silly but which, in the end, gets you there.
First off, Eric Idle's opening narration leaves you feeling that you're on some kind of second-rate Monty Python jaunt but, pretty soon thereafter, you hit the first of Neil Innes' brilliantly written and performed pastiches of Beatles' songs and things get much more impressive. And, from here on, it's a roller-coaster ride through some hilariously good and other, fairly weak re-workings of the Fab Four's career including brilliant send-ups of "Magical Mystery Tour", the Apple Corps debacle, "Yellow Submarine" and the "Get Back" rooftop session. But what makes this whole weird & wonderful ride hang together is the music... inspired, "tongue in cheek" gems that are so good that it's often difficult to remember they're not in fact original Beatles recordings. And, finally, the DVD's additional "deleted scenes" from the film's interviews with Mick Jagger & Paul Simon add fascinating insights into how The Beatles impacted on them while providing some wonderfully unintentional entertainment as they both struggle to remember that they should be talking about "The Rutles" rather than the real thing.
But what makes the film really interesting is that it's much closer to the reality of what actually went on than you may think. George Harrison's involvement as an actor in it, coupled with his close association with Eric Idle and the Monty Python team suggests that a great deal of "insider knowledge" was involved... how much remains a mystery in itself but the hand of someone "in the know" is most definitely there, making this flawed but highly entertaining film more than just an enjoyable spoof.
