In the most unique screening experiment we’ve heard of in a while (sorry, Jonah Hill), Magnolia Pictures and the Green Film Company will offer a pay-what-you-want preview of Freakonomics: The Movie on Sept. 22 for audiences in Los Angeles, San Francisco, Washington D.C., Chicago, Boston, Dallas, Philadelphia, Denver, and Seattle. The adaptation of Stephen Dubner and Steven Levitt’s best-selling book applies economics-based thinking to everyday human behavior, using a “dream team” of documentary filmmakers like Seth Gordon (The King Of Kong), Morgan Spurlock (Super Size Me), and Alex Gibney (Enron: The Smartest Guys In The Room) to examine everything from Sumo wrestling to baby names to students who are paid to study harder, and by participating in this screening—which requires filling out a short questionnaire—you’ll actually become part of a Freakonomics study yourself, in keeping with the book’s examination of how people interact with a pay-what-you-want bagel service.
