This is an expansive, rib-tickling, and subversive comedy in which Moore, playing the role of "invader," visits a host of nations to learn how the U.S. could improve its own prospects. The creator of Fahrenheit 9/11 and Bowling for Columbine is back with this hilarious and eye-opening call to arms. Turns out the solutions to America's most entrenched problems already existed in the world - they're just waiting to be co-opted.
