A mysterious fog roles into Antonio Bay.
The Fog is a guilty pleasure film of mine as I love how well the filmmakers develop the tension and tell a story with great cinematography, sound, and use of locations.
The plot is simple and full of dark cynicism about accepted histories, but it mostly just sets up creepy and suspenseful horror moments. Some aspects feel contrived, but it does not impact the entertainment if you do not take certain details too seriously.
I like how it creates a plausible small town community tied together by the soothing voice of the radio DJ character. I think this develops a sense of quaintness and enhances the vulnerability of the characters during the horror sequences.
Dean Cundey's cinematography is one of the highlights as there are some beautifully composed shots, and virtually every one feels spooky regardless of the content. When combined with the editing and sound, it works superbly. I usually cannot take my eyes off the screen when watching the opening scenes around the Antonio Bay as they give fairly mundane imagery of people and places a sense of impending dread.
As for the effects, you can see John Carpenter made the best use of a limited budget. You have to suspend the disbelief that a smoke machine is meant to be the fog and accept that several ghostly murderous figures are obscured by darkness for a good reason.
All actors are on good form, particularly Adrienne Barbeau and Janet Leigh. Jamie Lee Curtis and Tom Atkins have a good natural chemistry and their banter feels real. Hal Holbrook puts his heart into a key role and despite the silliness of certain aspects of the plot he pulls it off well.
