Driven by shame, Nazi child-abuser Klaus (Günter Meisner) jumps from a tower only to wind up incapacitated in an iron lung, exiled to Spain where he is attended to by his wife Griselda (Marisa Paredes) and daughter Rena (Gisèle Echevarría). When a young man, Angelo (David Sust),takes the position of Klaus's nurse/carer, the Nazi gets a taste of his own medicine, for Angelo is a victim of his patient's sordid past and he intends to reenact the nasty Nazi's crimes, as detailed in Klaus's wartime diary.

In A Glass Cage is often labelled as one of the most disturbing movies ever made, thanks to its extremely sensitive themes, but don't go expecting a graphic, taboo-busting, in-your-face shocker like A Serbian Film: the film's more controversial content is thankfully left to the imagination, while the murders of two youngsters are less exploitative than they easily could have been. However, as is often the case, this reserved approach only makes the matters more potent, the film lingering in the mind long after Angelo has done his worst.

7.5/10, rounded up to 8 for IMDb. While the very measured pace might be off-putting to some, fans of challenging horror should definitely check this one out.

In Spain, the former Nazi doctor Klaus (Günter Meisner) tries to commit suicide jumping off the roof of his manor. However, he survives with the entire body paralyzed and dependable of an iron lung with glass sides. His wife Griselda (Marisa Paredes) decides to hire a nurse since she does not bear the situation. Klaus asks Griselda to hire Angelo (David Sust),a mysterious teenager that appears in their house. Angelo befriends Klaus' daughter Rena (Gisèla Echevarría) and sooner it is shown that Klaus was a pedophile that loved to feel the fear of death in young boys before abusing and killing them. Further, Angelo is a disturbed and totally insane victim of his experiments that intends to follow the insanities described in Klaus' diary and incorporate his personality.

"Tras el Cristal", a.k.a "In the Glass Cage". Is one of the most dark, bizarre and disturbing films that I have recently seen. The cruelty of Klaus with the boys described in his diary is unthinkable and so sick that it is hard to believe that a normal person may have written this story.

The performances are top-notch and the conclusion is open to the most different interpretations. I understand that Angelo has followed the footsteps of Klaus and ended in the iron lung like his mentor. Rena is so disturbed with the revelations about her father that she is insane and will follow the footsteps of Angelo.

In the Extras in the Bonus Disc, the director Agustí Villaronga provides additional information about "In the Glass Cage", "Black Bread" and "The Sea" very interesting. My vote is eight.

Title (Brazil): "Prisão de Cristal" ("Cristal Prison")

Spanish ¨cult movie¨ with astonishing images and deliberately paced . This moving as well as strong story is an emotive recounting and an intense horror drama , including tragedy , deaths and bloody executions by hanging , stabbing and other means . After torturing and murdering his latest victim , a Nazi doctor named Klaus (Gunter Meisner) throws himself off a roof , all of it has been secretly witnessed by a little boy . Some years later, his suicide failed attempt , his wife Griselda (Marisa Paredes, Almodovar's ordinary) decides to contract a worker to care him . As Klaus is forced to be confined to an artifact contains an iron lung and to accept a mysterious boy called Angelo (David Sust) as his nurse under threat of blackmail . Meanwhile , Angelo befriends Klaus' daughter (Echevarria) , and the rare teenager possesses the Klaus's diary, which details his wartime experiments in concentration camps and his ulteriorly descent into pedophilia and killing .

The picture is full of suspense , mystery , screechy bursts of violence and lots of blood and gore . As this terror as well as claustrophobic flick shown to the audience gets more and more violent . This slick horror feast is a triumph of style over movie logic . It's packed with overwhelming as well as upsetting images , excessive violence and grotesque killings . Here is treated some disturbing issues such as fetish for young boys , pedophilia , sodomy , eerie tortures and grisly killings . Good acting by Gunter Meisner as former Nazi doctor-turned-pedophile , paralyzed from the neck down and who subsequently feels guilt . Günter Meisner originally turned down the role , horrified by the story . According to Villaronga , Meisner called him a few weeks later to accept the part, arguing he couldn't stop thinking about it . Gunter was a character actor who worked continuously in movies due to his aristocratic style , making him ideal for typecasting in British and later American films as Nazis and other vile , despicable roles , what was ironic about his typecasting as a Nazi is that he stayed in a Nazi death camp during World War II . Although well-known for playing Hitler and various others warlike movies , Meisner was a fine actor who played several support roles , being specially known for his secondaries in ¨The Boys from Brazil¨ , ¨Night crossing¨, ¨Ace of Aces¨ , ¨Avalanche Express¨ and his character as Mr Slugworth in ¨Willy Wonka & the Chocolate Factory ¨ . Furthermore , disturbing acting by David Sust as a boy secretly witnessed the doctor's torture , displaying his ambition to follow in the older man's footsteps and finally unleashes his own criminal spree .

Director/writer Agustí Villaronga said that the origin of the story came when he read about Giles De Rais (1404-1440),a devoutly religious follower of Joan of Arc who fought valiantly on her side and was later trialed and executed by the Catholic Church for heresy and sexual crimes committed against children . As Rais served as a commander in the Royal Army, distinguishing himself by displaying reckless bravery on the battlefield during the renewal of the Hundred Years War . He killed, or ordered to be killed , a great but uncertain number of children after he committed sodomy upon them . In fact , forty bodies were discovered in Machecoul , France , in 1437 . Gilles' body-servant Étienne Corrillaut , known as Poitou, was an accomplice in many of the crimes and testified that his master hung his victims with ropes from a hook . The victims were killed by decapitation, cutting of their throats, dismemberment, or breaking of their necks with a stick . Rais's prosecution would be on charges which included murder , sodomy, and heresy. The precise number of Gilles' victims is not known, as most of the bodies were burned or buried. The number of murders is generally placed between 80 and 200; a few have conjectured numbers upwards of 600 . The victims ranged in age from six to eighteen and included both sexes.

Downbeat and frightening musical score by Javier Navarrete . Dark as well colorful cinematography by Jaume Peracaula . This motion picture titled ¨In a glass cage¨ or ¨Tras el Cristal¨ was compellingly directed by Agusti Villaronga . Agusti was born in 1953 in Majorca, Balearic Islands ; he uses to make films including genuine chills , suspense , mystery and dark atmospheres . His movies pack excellent creation of taut , thriller , emotions and rare atmospheres such as ¨Aro Tolbukhin¨ , ¨El mar¨ , ¨El Niño De la Luna¨ also starred by Gunter Meisner and especially ¨Black bread¨ or ¨Pan Negro¨ , or Pa Negre¨ , this was his greatest success , winning several Goyas .
