Josh opens up about Scarlett

While doing press in London to promote Global Cool and climate change initiatives, Josh Hartnett spoke to a British newspaper about his split from Scarlett Johansson. "It was difficult spending so much time apart with all our different commitments and both of us flying all over the world," Hartnett said of his Black Dahlia co-star. "At the end of the day, we're just ordinary people and it didn't work." Of his support for Global Cool, Hartnett hopes he "can make a difference," and says, "It's very strange and makes a change from acting."
