If you live in NYC, Los Angeles, San Francisco, Washington D.C., Chicago, Boston, Dallas, Philadelphia, Denver, and Seattle, the people behind the film adaptation of best-selling book Freakonomics are offering you the chance to attend a pay-what-you-want screening of the movie on Sept. 22.

All you have to do to take part in this experiment is answer a few survey questions and pay anywhere from $.01 to $100 to see the film. After that, you’ll be directed to a movietickets.com page where you can buy the tickets — no service charge — online.
