this be very dated and very much of it time ( a capsule of the wing sixty ) . strangely set bound ( even the exterior scene be film on a set ) and it have the appearance or atmosphere of a stage play . for such a distinguish cast and there be more than a few shaky performance which make the direction suspect . not particularly enjoyable a a thriller and certainly not scary and why the dvd still carry an 18 certificate in the uk heaven only know . on any night of the week you can watch more explicit material than this on the main tv channel . only worth watch a a curiosity now i be afraid . one thing for sure and hywel bennett would certainly have be well keep his clothes on in the film and his pasty body isn not a pretty sight .
