Out of all "Hammer House of Horror" episodes, "The Silent Scream" was the one I was most looking forward to, and for good reasons. This seventh episode generally is the most anticipated one in the series, for starring the iconic Horror deity and Hammer-legend Peter Cushing (in my humble opinion one of the greatest actors who ever lived) as well as the great Scottish character actor Brian Cox (the first Hannibal Lecter). But even apart from the magnificent cast, director Alan Gibson's claustrophobic tale is by far the creepiest and most brilliant part of the 13-episode series, and it also ranks among the most chilling tales ever brought forth by the great Hammer Studios. The episode creates genuine creepiness by appealing to the primal fear of claustrophobia. Ex-convict Chuck (Brian Cox) comes out of prison, and visits Martin Blueck (Peter Cushing), an elderly pet-store owner who used to visit him in jail. Chuck is shocked, however, to find out that the kind old man has a sinister side, and a very macabre hobby... I don't want to give too much away, as all Horror fans should be able experience this macabre and spine-chilling tale for themselves, but I can assure that anyone who likes the show or Horror in general should better not miss this. Cushing is at his best in the role of the seemingly kindly elderly man who turns out to have an immensely sadistic side. Cox is also great in the lead, and Elaine Donelly is very good as his wife. Even though I still haven't seen the episodes "Charlie Boy" (Episode 6) and "The Mark of Satan" (Episode 13), I think it is safe to say that this is by far the greatest "Hammer House of Horror" episode, regarding acting, atmosphere and story-wise and a true must for all Horror fans. Not to be missed!
