Only recently unearthed in Australia. This exemplary, very low-budget transposition of 'The Desperate Hours' to a family caravan vividly shot almost entirely on location in Kent by cameraman/co.producer Monty Berman had obviously not been seen by either Quinlan or Chibnall & McFarlane when they wrote it up in their books, since they both describe it wrongly and grossly underrate it.
A lean, mean, moustached young John Colicos plays the fearsome zoot-suited killer on the run with a gun; and like most British films of the period it's enlivened by yet another familiar face every few minutes.
