Of all the performances, Samuel L. Jackson's is the most surprising. It sometimes appears that the busy Jackson will take almost any role to stay working. (Remember "Black Snake Moan"?) This film provides a reminder of his subtlety. He is a powerful, successful man, relatively helpless with a demanding and sexually skilled woman like Elizabeth. They like the sex, there is no love, she does not want to be involved in his personal life, and there is something there that disturbs him.
Bening, Watts and Washington create three distinct beings with three distinct lives. They don't all "share the same problem," but they believe they share the same solution. Garcia embeds their needs in the details of their lives, so we don't emerge with ideas about them, but feelings.
