Elizabeth Streb and Philippe Petit

Choreographer-stuntwoman-dancer Streb's latest book is titled Streb: How to Become an Extreme Action Hero, which chronicles her efforts to test her body and the powers of gravity. Considering her aesthetic, it's no surprise that she'll be discussing her fearless work today with Frenchman Petit, who is best known as the man who walked a high wire strung between the Twin Towers in 1974. Moderated by journalist and anchor Laura Flanders.
