Since then, she's received Oscar nominations for Dangerous Liaisons, The Fabulous Baker Boys, and Love Field. She also starred in Frankie and Johnny, Batman Returns, The Age of Innocence, One Fine Day, and I Am Sam. After some time away from the movies, she returned with a vengeance in star-studded fantasy Stardust and won rave reviews for her role as a courtesan in Cheri. More recently she's appeared in New Year's Eve, Dark Shadows and The Family, and claims she plans to work a lot now that her children are grown up.
