39-Across39ASee 21-Across[----]'s 75th birthday is tomorrow (May 20, 2021). Happy Birthday to an icon. The quote referenced in 21-Across21A"Mom, ____" (iconic 39-Across quote from a 1996 interview with 1-Across)[-----------] is iconic enough that Taylor Swift referenced it in a music video. The title of this puzzle has nothing to do with anything except it's one of my favorite movies and, of course, stars 39-Across39ASee 21-Across[----].
