The invisible Solitary Man...

Said Michael Douglas, star of the Solitary Man, "I like to flirt with that grey area not overtly being heroic or a villain. Just being human."

And Douglas brings humanity to an exceedingly difficult role that could get him an Oscar in an independent film. It shows you that the higher you are, the harder you fall until at the end you are invisible. People who once knew you don't return your calls; others are too busy to see you. He tries to cheat aging by chasing younger and younger women but as a character says to him, "You can't cheat death no matter how many 19-year-olds you talk into your bed".

Douglas's character Ben Kalman, once a reasonable celebrity as `New York's honest car dealer', has seen it all -the heights of fame, the depths of anonymity. Still charming, good-looking, still persuasive, he is invisible because now down on his luck, no one knows him.

Says Roger Ebert, "He isn't solitary by choice but by default. He cheated on his good wife Nancy (Susan Sarandon).

He disappointed their daughter, Susan (Jenna Fischer) one time too many. He cheats on his current companion, Jordan (Mary-Louise Parker), in a particularly unforgivable way. He uses charm and the offer of his experience in life to charm Daniel Cheston (Jesse Eisenberg), a college student, and then betrays him. He has lied to his customers so often that, as everyone knows, `Honest Ben Kalman' spent time behind bars.

Yet he's charming and persuasive. He looks like a winner until you look too close. Solitary Man follows him for several days after he agrees to ac company Jordan's daughter, Allyson (Imogen Poots), as she goes for a college interview.

This is the same school he attended. He knows the dean, which may be a help.

You want to like Ben. He works on encouraging that.

When he was younger and less of a sinner, he must have been good to know, and there's an effective character in Solitary Man who suggests that. This is his old buddy Jimmy (Danny DeVito), who still runs a greasy spoon diner. On campus, Ben befriends the naive Cheston with man-of-the-world advice about sex, success and how to sell yourself. With women, Ben's approach is solicitous: Do some men misunderstand you? Are your qualities recognised? What are you getting out of the transaction?

The film is all about Ben Kalman, but one of the strengths of Michael Douglas' performance is that he isn't playing a character. He's playing a character who is playing a character. Ben's life has become performance art. You get the feeling he never goes offstage. He sees few women he doesn't try seducing. As a car dealer, he was also in the seduction trade. His business was selling himself at a dealership. What about in life when you need a recall?

What happens with Ben and the people in his life, especially the women, I should not hint at here. The movie depends on our fascination as we see what lengths this man will go to.

Solitary Man is a serious comedy, perceptive, nuanced, with every supporting performance well-calibrated to demonstrate to Ben that he can run but he can no longer hide.

Here is one of Douglas' finest performances. Because the other characters, no matter what they think, never truly engage Ben, he's on that stage by himself. Everyone else is in the audience. Douglas plays Ben as charismatic, he plays him shameless, he plays him as brave, and very gradually, he learns to play him as himself.

That's the only role left."
