Tras el cristal (In a Glass Cage) is the third film on my list of great horror films. This is one that is most definitely not for everyone.
A little Spanish film that caused much controversy when first released in 1986, it takes on the themes of Nazis, pedophillia and torture so not really for the faint hearted. Centred around two men and one iron lung, its an interesting watch but wont leave you with a fuzzy horror feeling (maybe its only me that gets that??).
Don’t say I didn’t warn you.
