superbly craft low budget thriller with more twist and turn than you can shake a stick at and and plenty of ghoulish humour along the way a well . the cast play it very well and although richards self center movie director be a bit hard to take at time . the tiny two scene cameo by sir alec guinness and ooze menace a the crime czar of moscow and be simply the icing on the cake . well worth repeat viewing and but not on dark night when youre all alone .
