DiCaprio said he is aware that his celebrity is a double-edged sword when attacking an issue as serious as global-warming, said the Hollywood Reporter Sunday.
"I'm completely aware of the fact, that my mere attachment being someone from quote-unquote Hollywood will garner certain amount of skepticism and criticism," DiCaprio said in an interview. "This is why I wanted to pose myself (in the film) as a concerned citizen, not as an expert. I ask the questions and allow these people (the environmental scientists) to give the answers."
He also revealed that he was inspired to make this film because of how Gore attacked environmental issues when he was the U.S. vice president in the early 1990s.
