"The Hangover" actor and comedian Zach Galifianakis is working as the executive producer for a new documentary called "Craigslist Joe".
The movie is about Joe Garner, who traveled across America living off Craigslist ads.
Over 31 days, Garner sought transportation, food, and shelter through ads on the online classifieds network. All he took with him on the journey was a laptop, cell phone, toothbrush, and the clothes he wore.
The movie is slated to hit theaters and iTunes on August 2.
