Duchovny's characters have often had this dark sexual side: Mulder's main outlet was porn; the transvestite FBI agent on Twin Peaks, the Red Shoe Diaries. And he's been accused of sex addiction 10 years ago (before he was married.) (He denied it.)
The timing is either coincidental or ironic, or neither: season 2 of Californication-- his show about a sex addict, starts September 28.
Which then begs the questions: is this
- who he is, and chooses roles (or is able to do certain roles) based on his personality?
- not who he is, but becomes it because of repeated exposure to these roles?
- not who he is, but is using this as a publicity stunt?
- then his core identity is strong, and can only excel in roles where art imitates (his) life
- core identity weak, but would be a good actor in diverse roles as well OR could be a better actor by immersing himself in a character OR he (and Tea) should be careful of the roles he chooses
- core identity strong, Hollywood's products need every bit of help they can get
The image is not the real, but only a representation. But if there is no real, then that representation becomes the real.
I don't know whether he is a sex addict/good actor/strong personality, or not. But as I've said before, everyone must ultimately choose who they are, or else it will get chosen for you.
