Prophecy (1979)

Robert Foxworth (Damien: Omen II) and Talia Shire (Rocky, The Godfather) star as a doctor and his wife who travel to Maine to research the impact of the lumber industry on the local environment. They begin to investigate a succession of mysterious and terrifying events: ecological freaks of nature and a series of bizarre and grisly human deaths. Something unimaginably horrible waits in the woods … something unwittingly created by man, that will become an uncontrollable, merciless machine of destruction. Veteran director John Frankenheimer (The Manchurian Candidate) and writer David Seltzer (The Omen) presents "a gritty, violent, and deadly film that [packs] a death punch with very vivid, nightmarish special effects …" (Bloody Disgusting).
