‘Craving human flesh. Lusting for human blood’

Bog is a 1979 American horror monster movie directed by Don Keeslar from a screenplay written by Carl Kitt. The movie stars Gloria DeHaven, Aldo Ray, Marshall Thompson (First Man into Space, It! The Terror from Beyond Space) and Leo Gordon (Attack of the Giant Leeches).


When a local is fishing with dynamite in Bog Lake, something larger pops to the surface: a green bug-eyed monster awakened from a long sleep, which promptly begins killing fishermen who stumble across its lair. When biologist Ginny Glenn (Gloria DeHaven) discovers the creature’s evolutionary nature, the local sheriff decides to use various methods to destroy the beast…

“Technical competence hits the dirt (butter knife edits, awful compositions) and things drag towards the end, but that’s all right. The regional silliness, library music pilfering, and kaput budget drop the film somewhere between a Monster Kid Home Movies outtake and the earlier Night Fright. Kill scenes are ridiculously dramatic. The monster suit fails on all levels. Frequent bursts of hilarity courtesy Mr. Ray and Chuck detach all strings; even if you fall asleep, you’ll feel pretty good about it.” Bleeding Skull!

” … Bog is a silly, ineptly made film, and at times it’s an awfully tedious one, too. But because it’s also one of those movies in which virtually everything seems subtly out of whack in ways that ordinary forms of badness can’t explain, I find myself positively disposed toward it nonetheless.” 1000 Misspent Hours and Counting

“Bog is so derivative and formula-bound it could have been blocked out by stencil. The entire catalogue of pulp SF/horror/monster stereotypes and cliches are paraded past us, from retarded hillbillies to arseholish deputies. Thompson and De Havens ‘touching’ geriatric smooch interlude is a corny lowlight (?) that will have you wondering if you unwittingly stumbled into “On Golden Bog”…” Les Moore, Monster! issue 18


Bog received a limited release theatrically in the United States by Marshall Films in 1983 and was subsequently released on VHS by Prism Entertainment Corporation.
