One of the many silly books being published for Halloween is The Horror Film Quiz Book. The questions are organised by film, though it might have been as well to categorise them according to difficulty. They range from the absurdly easy – 'who directed the original Psycho?' or 'For his main female lead roles Hitchcock chose girls with what hair colour?' – to the uttery impossible for anyone except the most committed horror nerd: 'What type of chainsaw was used in Texas Chainsaw Massacre?' Winter evening fun for all the family.
