Anyone with only a cursory awareness of David Lynch’s work might wonder just what the hell The Wizard of Oz has to do with the famously avant-garde auteur’s filmography. The short answer is: a lot. As recounted in the 2022 documentary Lynch/Oz, the man behind Twin Peaks and Blue Velvet once told a crowd of cinephiles, “There’s not a day that goes by that I don’t think about The Wizard of Oz.” Most fans know that few things beguiled and transfixed Lynch as much as the splendor of Old Hollywood, and his work is packed with direct and indirect references to Victor Fleming’s groundbreaking 1939 film — from the aesthetic (like Laura Dern’s red shoes in Wild at Heart) to the thematic (various characters’ longing to return home). As part of the theater’s ongoing series David Lynch: A Retrospective, the Belcourt will show both the aforementioned documentary Lynch/Oz — directed by Alexandre O. Philippe — and Fleming’s cinematic masterpiece. The pair will show as a doubleheader midday Saturday, with more screenings of The Wizard of Oz to follow Saturday night and Monday evening.
