The upcoming Tom Hooper film adaptation of “Les Misérables” is the most recent showcasing of actors’ singing abilities. While Hugh Jackman, Amanda Seyfried, Russell Crowe, and Helena Bonham Carter—even Anne Hathaway in “Ella Enchanted” —have already proven themselves talented singers, the new musical adaptation will challenge their abilities even further. For the first time ever in a musical film production, the actors of “Les Mis” will be singing their numbers live on set instead of lip-syncing over a track, as most musical films are made.
