When Karl Lagerfeld does a documentary, it's Karl Lagerfeld spouting in front of the camera for two hours. Valentino isn't like that. He's not very verbally expressive. He's very controlled and he needs to be perfect all the time - never a hair out of place, always the impeccable outfit.

Valentino Garavani is never really shown himself as anything other than this gracious diplomat of the dolce vita. That's his preferred look. But he's a temperamental genius - a man of cyclone force, passion, and perfectionist impulses who has very little tolerance for things that aren't exactly as he wants them to be.

Giancarlo Giammetti has a lot of nervous energy. He's a director, really. He was trying to direct the Valentino movie over my shoulder. I don't blame him - that's been his job for 50 years. But I had final cut in the movie by contract and I wouldn't have made the movie if I had not been completely independent.

They would sort of keep you on your toes that way - that kind of Italian allergic reaction to eagerness. It's very bruta figura, bad form, to be eager. You sort of glide in and have a conversation and work things out, then it takes two days to get up and running.

Valentino lives his life like the Queen of England - he lives in the bubble. But he designs for royals, so it's almost a business decision, even though he would do it anyway. He wants to be part of that world.

His home life is as ordered and complex and sophisticated as his work life. You don't find creations like this anymore. The Leopard comes to mind - this tale of a glorious, lost Italy. That's Valentino.

Ralph Lauren and Valentino have a lot of common. Ralph Lauren was one of the first really to put himself at the center of the story, and Valentino was even earlier.
