The Night Strangler
is the sequel to the enormously successful 1972 TV movie The Night Stalker
. Darren McGavin returns as seedy reporter Carl Kolchak, who previously ran into conflict when Las Vegas authorities refused to acknowledge Kolchak's uncovering of a modern-day vampire. Now he's in Seattle, on the trail of a mysterious strangler who drains the blood of his victims. Kolchak's quest takes him to a hidden underground city beneath Seattle and the bizarre residents therein. Margaret Hamilton (The Wizard of Oz
) is seen briefly as an expert on alchemy; John Carradine also makes cameo. The success of this telemovie and its predecessor inspired a brief 1974 TV series, Kolchak: The Night Stalker
, also starring McGavin.
