Quote:
tells that Karloff's scenes for LA CAMARA DEL TERROR / THE FEAR CHAMBER were shot in February, 1968, followed by LA MUERTE VIVIENTE / SNAKE PEOPLE. But for the two others, SERENATA MACABRA / HOUSE OF EVIL and INVASION SINIESTRA / SINISTER INVASION, I don't know the exact chronology.
The first one filmed was, without question, INCREDIBLE INVASION. I'm not certain of the order of the other three, but I am about that one. I >think< the next was SNAKE PEOPLE, then HOUSE OF EVIL, finally, THE FEAR CHAMBER.
