It’s fitting that L’Amour Fou, Pierre Thoretton’s portrait of designer Yves Saint-Laurent—particularly focusing on his 50-year romance with Pierre Bergé—begins with Saint-Laurent’s dignified farewell to the fashion industry, since the movie mainly serves as a fond valedictory. Framed by Berger’s preparation for a massive auction of the couple’s copious belongings, the film bids goodbye to its subject piece by piece, but the pieces don’t always come together. The pair met as Saint-Laurent was assuming the mantle of the late Christian Dior, with (judging by this account) the fate of the fashion world resting on his slim shoulders. In retrospect, his ascension is a fait accompli, and the backward-looking approach doesn’t bring the drama of that moment to life. Archival footage crammed with famous hangers-on (Mick Jagger, Andy Warhol, Jean Cocteau) brings some sense of those days to life, but for the most part, watching L’Amour Fou is like listening to someone reminisce about the good old days; it’s intriguing, but viewers can be forgiven for checking their watches.
