The Fog is a 1980 horror film directed by John Carpenter, who also co-wrote the screenplay and composed the music for the film. It stars Adrienne Barbeau, Jamie Lee Curtis, Tom Atkins and Janet Leigh. It tells the story of a strange, glowing fog that sweeps in over a small coastal town in California, bringing with it the vengeful ghosts of mariners who were killed in a shipwreck there exactly 100 years earlier.
The Fog was Carpenter's first feature film after the success of his 1978 horror Halloween, which also starred Jamie Lee Curtis. Though not as big a success as Halloween, the film received some good reviews (with a 68% positive rating on Rotten Tomatoes) and was also a commercial success. A remake of the film was made in 2005. It was Carpenter's last horror film before his film The Thing and began a trend continued with Carpenter's contributions to Halloween II, Halloween III: Season of the Witch and The Thing of substituting his own suggestive violence with explicit gore.
