Dolly Parton is a genuine American icon. For her 75th birthday, we revisit the country superstar and EGOT nominee’s three most significant film roles in “9 to 5” (1980), “The Best Little Whorehouse in Texas” (1982), and “Steel Magnolias” (1989). Also, thank you for funding the Moderna vaccine, Dolly; we will alwaaaaaays love you.
