IMDb blurb "The final scene of a film has been lost and the extras have to be rounded up for it to be re-shot." Really? Yawn.........
With token Yank Richard Basehart in a leading part and that awful 1950s colour, I totally lost interest in this after about ½ hour and watched summat else.
Well known faces I saw were Sid James, who never looks any different, a very thin faced Patrick Cargill and very young looking, with mop of hair (!) (the Rev. Timothy Farthing) Frank Williams, but none could save it.
Don't bother - read a comic, Dandy or Beano would have more humour in them.
