Hayden Panettiere plans to make a movie documentary about her close-heart cause: the whales. The Heroes star has revealed she wants to do something similar to US vice president Al Gore’s An Inconvenient Truth about sea world. The 18-year-old actress, who headed the Save The Whales Again’s campaign, has flew to Washington to discuss with Japanese, Icelandic and Norwegian embassies about their hunting practices. She told UK magazine Grazia, “It's going to be the Inconvenient Truth of the oceans."
