Played By: David Duchovny
Hottest Conquests: Karen van der Beek (Natascha McElhone), Heather the Nun (Michele Nordin)

If ever there was a character to perfectly illustrate the difference between a sex addict and an old fashioned seducer, it's Hank Moody (David Duchovny), the troubled but talented novelist at the center of Californication. For Moody, the challenge—and excitement—of sex is in the seduction.

And he's had plenty of practice at it, sleeping with just about every female character on the show. But to understand the sex addict, one only need to look at Duchovny himself who, after more than a decade of marriage to actress Téa Leoni, checked himself into rehab for sex addiction in 2008. Let's just call it a case of Method acting.
