Mia has bowed out of the lesbian love-affair drama “Carol”, with Rooney Mara stepping in to replace her.

“Carol”, directed by Todd Haynes (“Far From Heaven” and “I’m Not There”), depicts an unhappily married woman in 1950s New York (Blanchett) who longs to leave her husband behind but fears losing her daughter. She falls for a department-store employee who also pines for a better life (Mara).

The movie is based on the novella “The Price of Salt,” by “The Talented Mr. Ripley” scribe Patricia Highsmith. The script comes from Phyllis Nagy (HBO’s “Mrs. Harris”), with production slated to begin in spring 2014.
