Nature Boy McGregor's character, Christian. Some of the film's premise was based on the lyrics, in particular the opening lines. The closing lyric, "The greatest thing you'll ever learn is just to love and be loved in return" is used throughout the film. While reviewing "Moulin Rouge!", Erickson noted that "[by] itself, ['Nature Boy'] redeems the wonderful idea behind Luhrmann's flawed but often wonderful movie." The song was performed by Rodrigo Santoro in the film "Heleno" (2012), during the radio interview when he asks if he could sing a song for his wife and son. Cole's version was again played at the
To Be (song) boy looking towards the camera, until shifting to Hamasaki wearing a colorful outfit whilst surrounded by star-like shapes. The boy walks through the stars whilst Hamasaki sings the song; the second look is inspired by the artwork of "To Be". He opens a case that holds a kaleidoscope and looks through it, seeing various versions of Hamasaki in different colored outfits and wigs singing the song. All these scenes start to re-appear throughout the rest of the song, and ends with a black and white image of Hamasaki, apparently cracked in the kaleidoscope, which then has the boy looking upset.
