Pedro Almodovar insisted on featuring flatulence in new movie VOLVER - because he finds farting deeply meaningful. The Spanish director values the earthy side of life, and believes the fragrance of a fart can be an emotional trigger. He says, "In my own life, my friends do it in front of me. "It's an important moment in Volver. It's when she (Penelope Cruz) is on the toilet that she can smell her mother's farted, it's that very personal smell. "That's something very emotional for me, because when my mother farted, she used to burst out laughing."
