Sure Sean Penn did some cool things back in the day: He banged Madonna (when she was still cheap and hot looking), starred in the teen classic Fast Times at Ridgemont High, and constantly scuffled with the paparazzi. These days, however, Penn’s channeled his hotheadedness into political activism, writing convoluted open letters to the Bush Administration (hearing him read one was akin to watching his performance in I Am Sam), allying with outspoken U.S. opponent Hugo Chavez, and driving a boat around a flooded, hurricane-ravaged New Orleans like it was a damn movie set.
