Filmed in England, Someone at the Top of the Stairs stars Donna Mills and Judy Carne as a pair of American tourists roaming at large in London. Taking rooms in a Victorian-era boarding house, Mills and Carne are terrified by the house's weird inhabits. Be assured that there's worse to come in this updated derivation of the 1944 mystery film The Night Has Eyes. Someone at the Top of the Stairs was first telecast in Great Britain in 1973, then shipped out to American television a few months later. It debuted in the US as part of ABC's Wide World Mystery anthology series.
