After impulsively declaring his retirement from acting in the fall of 2008 after wrapping the film 'Two Lovers,' Joaquin Phoenix gained a natty beard and a paunch, chased a new career as a hip hop artist and looked depressed and druggy on a February 2009 appearance on the 'Late Show With David Letterman' that was widely viewed on the Internet. Now that the world at large sees the 35-year-old actor as a basket case, Phoenix will need to do some serious repair work to reemerge from this two-year career hiatus. (The fact that his gifted, troubled older brother River died of a drug overdose does not help his case.)
