I'm convinced he's gay.
Not only due to his awkward marriage, but the fact he just gives off such an effeminate vibe/has an effeminate voice in many of his films (Savages comes to mind).
I can't be the only one who gets a "gay" vibe from him. And it perfectly explains his attraction to Sam Taylor-Wood. She's not as ugly as everyone says (namely jealous fangirls), but she's a bit masculine in the face.
