The most difficult category of the year, because it truly is a murderer's row. Three of these actresses were nominated for their first and only time: Eve Arden, who went on to fame and fortune on television; and teenage actresses Ann Blyth and Joan Lorring, both playing "bad girls" in different degrees and accents. The other two were returning nominees. Angela Lansbury had just made her film debut the year before and already found herself a two-time nominee. Anne Revere had been nominated for The Song of Bernadette two years prior, but it was her role as the mother in National Velvet that won her the Academy Award:
She was nominated again for Gentleman's Agreement two years later, but the Red Scare effectively blacklisted her for twenty years. What a stupid time. Anyway, here are the nominees for 1945's Best Supporting Actress:
Eve Arden, Mildred Pierce
Ann Blyth, Mildred Pierce
Angela Lansbury, The Picture of Dorian Gray
Joan Lorring, The Corn is Green
Anne Revere, National Velvet
In Mildred Pierce, Eve Arden is the wisecracking friend and co-worker, while Ann Blyth is the traitorous, ungrateful daughter. In The Picture of Dorian Gray, Angela Lansbury is the saloon singer who maintains her innocence and, disastrously, falls in love with the titular heel. In The Corn is Green, Joan Lorring is the uncouth daughter of a schoolteacher's housekeeper who presents a challenge for the household and its hopes for the young Welshman they hope to make a writer of. And Revere is Momma to Liz Taylor.
