Yves Saint Laurent left a fashion legacy. He also left behind an extraordinary collection of art. In L'amour fou, Saint Laurent's partner in business and life, Pierre Bergé, made the choice to auction off the collection after Saint Laurent's death in 2008. It was considered "the auction of the century." Bergé talks about their relationship in both respects—from meeting Saint Laurent after his dismissal from Dior to starting up their fashion house and, of course, the art that they amassed. The collection started in the 1950s and included works ranging from Picasso and Matisse to Egyptian sculptures.

The art collection is impressive, but it represents more than just two collectors—they're the puzzle pieces that form a picture of a unique, half-century partnership. Carefully crafting a loving and well-deserved tribute, director Pierre Thoretton stunningly blends Bergé's interviews, rare archival footage, and incredible access to their homes to make what amounts to more than a biography. He captures a love story—a so-called crazy love—of art, fashion, and the two men who loved both and one another.

L'Amour Fou is currently being premiered at the Tribeca Film Festival. www.tribecafilm.com
