Go Away With … Bruno Coulais

French composer Bruno Coulais is used to helping convey a film’s tone with his music. But for “Babies” — which focuses on four tiny, chubby and (for a while) bald stars — the 56-year-old Parisian, best known for the 2009 stop-motion film “Coraline,” had his work cut out for him. The documentary features no dialogue from its main stars, so Coulais’ compositions at times have to speak for the infants. “Babies” is now available on DVD.
