Movie: Coma (1978)

Tagline: Imagine your life hangs by a thread. Imagine your body hangs by a wire. Imagine you're not imagining.
Trivia: The building used for the exteriors of the evil medical facility is actually the former Xerox Lexington, Massachusetts sales office, located about 10 minutes from downtown Boston near the intersection of routes 2 and 128. It is now the headquarters of Stride Rite footwear. The building has been altered since 1978 but is largely unchanged.
Goofs: Anachronisms: The ambulance driver states that he has to go through the Sumner Tunnel to get to Logan Airport. Since 1961, the tunnel going to Logan has been the Callahan tunnel. The Sumner tunnel has been outbound from the airport since 1962.
“A young woman doctor discovers something sinister going on in her hospital. Relatively healthy patients are having ‘complications’ during simple operations and ending up in comas. The patients are then shipped off to an institute that looks after them. The young doctor suspects there is more to this than meets the eye. Written by Colin Tinto <cst@imdb.com>”
