It was a massive gamble. Tom Hooper, fresh off his Oscar win for The King’s Speech, decided that the cast of the film Les Miserables wouldn't just lip-sync to pre-recorded tracks. They’d sing live. Every single take. On a drafty set with earpieces feeding them a remote piano.
People thought he was nuts.
Honestly, looking back at the 2012 production, that decision is exactly why the performances feel so raw, even if the vocal technique makes theater purists cringe. When you watch Hugh Jackman's veins bulging in his neck during "Soliloquy," you aren't hearing a polished studio session. You’re hearing a man who hadn't drank water for 36 hours to look "suitably haggard" for the opening scenes.
The Heavy Hitters: Hugh Jackman and Russell Crowe
Hugh Jackman was basically born to play Jean Valjean. He has that rare mix of "I can lift a literal cart off a man" physique and "I can hit an A4 in falsetto" range. He’s the anchor. But the casting of Russell Crowe as Inspector Javert? That’s where things get divisive.
Crowe isn't a Broadway singer. He's a rock-and-roll baritone. While some critics tore him apart for his "thin" vocals compared to stage legends like Terrence Mann or Philip Quast, there’s an argument to be made for his restraint. Javert is a man of rigid law and zero flexibility. Crowe plays him like a statue that is slowly cracking. His "Stars" might not have the operatic boom you’d expect at the Queen's Theatre, but it has a weird, haunting stillness.
It’s about the acting.
If you want perfect pitch, buy the 10th Anniversary Concert CD. If you want to see a man realize his entire moral code is a lie before jumping into the Seine, Crowe actually delivers a pretty nuanced performance. He didn't try to be a musical theater star; he stayed a film actor who happened to be singing his dialogue.

Anne Hathaway and the 20-Minute Oscar
Anne Hathaway’s screen time as Fantine is shockingly short. She’s in the movie for maybe twenty minutes? Yet, she walked away with the Academy Award for Best Supporting Actress, and it wasn't even a close race.
"I Dreamed a Dream" is usually a soaring, aspirational power ballad. Hathaway turned it into a jagged, snot-crying funeral dirge. The camera stays in a brutal, unbroken close-up. You see the jagged haircut—which was real, by the way, she actually let them chop her hair off on camera—and the physical decay.
The Cost of Realism
To get into the headspace of a dying factory worker turned prostitute, Hathaway reportedly lived on a diet of "dried oatmeal paste." She lost 25 pounds. She looked genuinely ill. That level of commitment from the cast of the film Les Miserables set a bar that few movie musicals have touched since. It wasn't about being pretty. It was about the "miserable" part of the title.
The Love Triangle and the Next Generation
Then we have the kids. Eddie Redmayne as Marius, Amanda Seyfried as Cosette, and Samantha Barks as Éponine.
Barks was the only one coming straight from the stage. She had played Éponine in the West End and at the 25th Anniversary Concert. You can tell. Her "On My Own" is arguably the most "perfect" vocal in the film because she had the muscle memory to sing while walking through fake rain in a corset that was reportedly tightened so much it made her lose feeling in her arms.
Redmayne, long before he was chasing fantastic beasts, brought a frantic, shaky vibrato to Marius. "Empty Chairs at Empty Tables" is a highlight because of his facial acting. He looks like a guy with survivor's guilt, not a leading man waiting for his applause.

- Eddie Redmayne: Used his background as a choral scholar at Eton to handle the live singing.
- Amanda Seyfried: Had the difficult task of playing the "ingénue," a role that is often boring, but she gave Cosette a certain high-strung anxiety that made sense for a girl raised by a fugitive.
- Aaron Tveit: As Enjolras, Tveit brought actual Broadway power. He was the "glue" for the student revolutionaries, providing a vocal stability that the non-pros lacked.
The Thénardiers: A Dark Comedy Break
Sacha Baron Cohen and Helena Bonham Carter. They’re basically playing the same "gross, chaotic duo" energy they had in Sweeney Todd, but it works. "Master of the House" is the only time the movie lets you breathe.
They’re disgusting. They’re thieves. They provide the necessary cynicism to balance out Marius’s starry-eyed idealism. Interestingly, Cohen reportedly improvised a lot of the physical comedy, which kept the rest of the cast on their toes during those long, live-singing takes.
Why the Live Singing Experiment Still Matters
Most movie musicals—think Chicago or The Greatest Showman—use "pre-lay." The actors record in a studio, then lip-sync on set. It allows for perfect vocals.
The cast of the film Les Miserables didn't have that luxury. If they wanted to pause for a sob, the pianist (listening through headphones) had to pause with them. This gave the actors total control over the pacing. They weren't slaves to a pre-recorded beat.
The result?
It’s messy. Sometimes the breathing is too loud. Sometimes the pitch wavers. But it feels human. In a world where AI can now generate a "perfect" singing voice, the flaws in the 2012 film are its greatest strength. You hear the effort. You hear the cold air in their lungs.

The Legacy of the 2012 Ensemble
When you look back at the cast of the film Les Miserables, you're looking at a snapshot of 2010s A-list power. You’ve got a future Wolverine, a future Glinda (Seyfried), and a future Newt Scamander.
But beyond the star power, the film succeeded because it treated the source material like a gritty historical drama rather than a "show." Colm Wilkinson, the original Jean Valjean from the 1985 London production, even makes a cameo as the Bishop of Digne. It’s a passing of the torch. It acknowledges that while the medium changes, the core of these characters—the grace of Valjean, the desperation of Fantine—remains constant.
Actionable Insights for Fans and Students of Film
If you're revisiting the film or studying it for the first time, pay attention to these specific elements that defined the production:
1. Watch the "Empty Chairs at Empty Tables" Close-up
Observe Eddie Redmayne’s breathing. Because it was recorded live, he uses the breath as a percussive element of grief. This is almost impossible to replicate with dubbing.
2. Compare the Vocal Textures
Notice the difference between Aaron Tveit (trained Broadway) and Russell Crowe (self-taught rock). The contrast highlights the class and personality differences between the characters—Enjolras is a polished leader; Javert is a blunt instrument of the state.
3. Check the Background Actors
Many of the revolutionaries and factory workers were actually West End performers. This ensured that the "wall of sound" in songs like "Do You Hear the People Sing?" had the necessary power to back up the Hollywood leads.
4. Listen for the "Imperfections"
Listen for the cracks in Anne Hathaway's voice during the final verses of "I Dreamed a Dream." These aren't mistakes; they are deliberate acting choices enabled by the live-recording format. It turns a song into a monologue.
The 2012 adaptation isn't a replacement for the stage show. It’s a companion piece that uses the intimacy of cinema to show the sweat, dirt, and tears that a theater audience can only see from the front row. The cast didn't just sing the roles; they lived them under some of the most grueling technical conditions in modern musical cinema.
