"Heaven," from Haynes' original script, was inspired by the coded Hollywood soap operas of '50s director Douglas Sirk, but the less complicated plot of "Carol" comes from "The Price of Salt," a 1952 novel of same-sex romance originally published under an alias by suspense specialist Patricia Highsmith, famed writer of such cinema-ready classics as "Strangers on a Train" and "The Talented Mr. Ripley."
It’s also a slightly different approach to the ’50s for director Todd Haynes, who previously explored the era’s spirit-crushing repression in 2002’s hugely acclaimed Far From Heaven .
Carol feels like the third part of a loose trilogy — preceded by Far from Heaven and his HBO miniseries adaptation of Mildred Pierce — of films set in the past, about women who are trapped by the confines of their time.
