Papers in Sean Penn's hands shook at times as he gave an emotional speech in Chicago on Wednesday.

"I'm trembling and I like it," Penn said after accepting the 2012 Peace Summit Award from former Soviet President Mikhail Gorbachev, who was joined on stage by the Dalai Lama and former Polish President Lech Walesa, reports AP. Penn, who spends at least half his time in Haiti, used his speech to urge the world community to remember Haiti, devastated by a January 2010 earthquake.

"He actually exchanged his home in Malibu for a tent," said Udo Janz, United Nations high commissioner for refugees, when he introduced Penn to accept the award. "Think of it as the Oscar for your humanitarian commitment, Sean."
