my father take me to see this film when it be release in 1976. i be but a child and it scar the crap out of me . so much so that i have to leave the theatre during a particularly claustrophobic tunnel scene a it be too intense for me . i go home to the safety of my family . i saw the film all the way through a i get old and thoroughly enjoy it . shame about the men in monster suit and though . if you overlook the cheapness of the production and delve deep and you will find an excellent performance by cushing and a stunning opening score and some nice photography and the ever reliable mr. douglas mcclure and my childhood hero . british police constable guard the whitehouse at the end . titty bang bang cave woman . monster with beak . actor in monster suit glide on wire . this have it all . superb .
