This is a very strange little film indeed.
On the one hand we have an already outdated storyline of hippies protesting against the establishment, then a rather weak effort at a 70s bed-hopping sex comedy, to an attempt at social commentary.
I tend to think that it borrows somewhat from the previous year's O Lucky Man in that the main character, completely lacking Malcolm McDowell's charisma, is an innocent thrust into a corporate world through a series of twists and turns.
If the fevered dream sequence in the windmill had been real - the film would have made sense.
The best parts, and I suggest they were added late in the process to rescue the production, are the brilliant acting of Wilfred Hyde-White and splendid cameos by Spike Milligan, and especially Terry-Thomas.
