“Valentino: The Last Emperor” is a feature-length film on the legendary designer Valentino Garavani in the wake of his exit in 2008 from the company he founded in Rome more than 45 years ago. Produced and directed by Matt Tyrnauer, Special Correspondent for Vanity Fair magazine, the film is an intimate, engaging and very funny fly-on-the-wall exploration of the singular world of one of Italy’s richest and most famous men. The film documents the colorful and dramatic closing act of Valentino’s celebrated career, tells the story of his extraordinary life and work, and also explores the larger themes affecting the fashion business today. But at the heart of the film is the unique relationship between Valentino and his business partner and companion of 50 years, Giancarlo Giammetti.
