the frozen dead (1967)

"The human is much more complex."
High ranking Nazi's are frozen and secreted about the world, as they realise they are losing the war. Twenty years later Nazi scientist Dr Norberg (Dana Andrews) sets out to revive them. But unfortunately they all come out brain-damaged, some would say they were brain damaged from the start! To determine what is going wrong he needs a healthy brain to experiment on, and a friend of his niece, Elsa (Kathleen Breck) is chosen. But Jean Norberg (Anna Palk) is suspicious of the sudden disappearance of her friend, a friend who has been condemned to a living hell, tortured as a head in a jar.
A film whose premise reads like a typical horror, but is infused with a despair and sadism, that is hard to forget.
