Two early Pete Walker films for the price of one, both presented in 1.33:1 ( not 'widescreen' as the Amazon description has it ), included are 2 versions of 'The Big Switch'- a shorter domestic version & a longer export version which includes a Black stripper routine during the opening credits, longer sex scenes, more nudity & a pathetic would-be torture scene featuring an unlit cigar.
'The Big Switch' is a thoroughly amateurish attempt at a gangster film, pathetically dated ( as is 'Moon' ) for 1968, considering 'Performance' was made about the same time. This sleazy production boasts a pretty good jazz score by Harry South, a live appearance by 60s band Timebox & some pleasing photography, but it was just too badly acted & scripted to hold my interest. The Hanna Barbera-esque climactic shoot out, staged in a Brighton amusement arcade, is risible, with guns being fired indiscriminately for no apparent reason & a chase scene with lead actor Sebastian Breaks(!) and Virginia Wetherell actually running on the spot at one point.
Filming as Walker did entirely on location, it's the garish period decor that takes centre stage, rather than the hopeless script, inept casting & not particularly attractive abundance of female flesh on display. Promising far more than either is able to deliver, both films were well past their sell-by date when they were made in the late 60s...today they exist as naff ( in Walker's words ) period pieces.
