Description from The Advocate magazine's The Top 175 Essential Films of All Time for LGBT Viewers:

The Adventures of Priscilla, Queen of the Desert (1994): Director Stephan Elliott's Australian film about the adventures of two drag queens and a trans woman who travel across the desert in a rickety old bus to perform a drag show found box office success around the world and a place in the hearts of many LGBT viewers as well. Starring Hugo Weaving, Guy Pearce, and Terence Stamp, the film garnered many awards, including an Oscar for Best Costume Design. Today, the film is considered by many to be an LGBT kitsch comedy classic, loved as much for its over-the-top characters as its unflinching look at life through a queer lens. -J.P.
