• This is the theme song for the 2009 James Cameron directed movie, Avatar. Lewis told the Canadian newspaper Sun Media that she is thrilled to have a song on the soundtrack. "I saw a half-hour clip of the film. It's not finished yet, and it's insane, it's awesome, it's amazing. I can't even explain it," she said. "I heard the song - great lyrics, very, very epic. So I went in and I did it. And then they played it to James and he phoned me up and he was like, 'Oh, my God. I love you!' He's so cool. My God, I had this perception that he was going to be, like, totally untouchable and unreachable. But he's just like your nice uncle. He's lovely."
• This was written by James Horner and Simon Franglen. Horner is a composer who scored the music for Avatar as well as James Cameron's earlier films Aliens and Titanic; Franglen is a producer who has worked on the soundtracks for many films, including Titanic.
