In S1E14, Lorelai tells Sookie that she named Rory’s chick “Stella” after “A Streetcar Named Desire.” Sookie asks, “Vivian Leigh or Jessica Tandy?” Lorelai answers, “Hello! Tandy!”
Vivian Leigh was the actress who played Blanche in the 1951 film adaptation of “A Streetcar Named Desire” (also discussed here).
Jessica Tandy played Blache in the original Broadway production of “A Streetcar Named Desire” in 1948 alongside Marlon Brando. Her performance earned her a Tony Award.
