A massive favourite of Stephen Thrower and a huge recommendation from me too (for what that's worth) -
Death Bed - The Bed That Eats - an absolutely superb underground gem from the 70s.
I also came across two books this morning in a second hand shop:
Landis's
Monsters In The Movies for a bargain £10 and Danny Peary's third volume of
Cult Movies, which has a fascinating piece on
Liquid Sky. this was only £4.50 and I pounced on it as the cheapest copy on Amazon Marketplace is
£75!!!
