Hell is Empty is a 1967 British crime film directed by Bernard Knowles and John Ainsworth, and starring Martine Carol, Anthony Steel, Shirley Anne Field and James Robertson Justice.
It was Martine Carol's first movie in three years[4] and one of a number of films Steel made in Europe.
[8] The Monthly Film Bulletin wrote: "The nonsensical story, which ten years ago might at least have had an overtone of reality within a small budget black-and-white framework, has here exploded into sumptuous colour, extravagant locations and a gimcrack way with camera zooms.
But beneath the reconditioned exterior, the old-fashioned gears set up an awful grinding: the crooks are a coarse lot, their robbery is by modern standards very rudimentary, and their hostages make a determined English parlour setting out of their indeterminate foreign locale.
James Robertson Justice's Shakespearian authority is as tedious as his usual blustery impersonations; but no one could be expected to perform any miracles with the dilapidated dialogue, and no one does.
