How Indiana Jones’s Fedora Became an Artifact With a Life of Its Own

2020’s summer blockbuster season has been put on hold because of the pandemic, but that doesn’t mean we can’t celebrate the movies from the past that we flocked out of the sun and into air conditioning for. Welcome to The Ringer’s Return to Summer Blockbuster Season, where we’ll feature different summer classics each week.
Three decades after Indiana Jones uncovered the lost Ark of the Covenant, Deborah Nadoolman Landis began her own archaeological expedition.
Tasked with curating a Hollywood costume exhibition for London’s Victoria and Albert Museum in 2012, the Raiders of the Lost Ark costume designer knew she needed to include her iconic creation: Indy’s signature fedora and brown leather jacket. So Landis, who’s also designed other classics from Three Amigos!, The Blues Brothers, and Michael Jackson’s “Thriller” video, visited Skywalker Ranch, where the movie’s producer, George Lucas, allowed her full access to his archives. When she asked an assistant to guide her toward Indiana’s wardrobe, she was met with a shrug.
