Short story in an anthology about a man who stops at a farm owned by a young woman who owns pigs. At the end we find out her name is Circe. I thought it was in a collection about the seven deadly sins...
This could be "Mrs. Hawk" by Margaret St. Clair.
It was originally published in the 1950 July issue of Weird Tales (available at the Internet Archive), and as @user14111 has pointed out, re-published in The Unexpected. Neither of them seem to be about the seven deadly sins.
From the script there is a pig farm
EXT. HOG FARM - NIGHT - FULL SHOT - (STOCK) Sparkling white house and outbuildings, neat fences and pens, etc., set back from the road which winds pleasantly through the moonlit valley below.
And that Mrs. Hawk is actually the Greek Goddess Circe:
I, Cissy Hawk, do confess that I am actually Circe, the Greek sorceress who changed sailors of Ulysses into hogs.
