Ginger Rogers steals the show as a selfish, snide Broadway superstar in Nunnally Johnson's Black Widow, preening, snooping, gossiping, and bestowing air kisses in equal abundance. Rogers is Carlotta Marin, a grande dame of the thea-tah, married, it would seem happily, to Brian Mullen (Reginald Gardiner). Yet at the heart of Black Widow is something grim, the death of a young, ambitious writer named Nancy (Peggy Ann Garner), who gloms onto a theater producer (Van Hefflin), who's in love with his wife, Iris (Gene Tierney, heartbreakingly lovely). Nancy's death appears to be self-inflicted, and yet as each piece of evidence--a weird suicide note, a threatening letter received in the mail--piles up, things begin to point to murder.
