ussell Crowe has been taking some heavy hits for his singing performance in Les MisÃ©rables. A San Francisco critic remarked that Crowe can't sing to save his life. An Australian writer commented in The New York Times: Hugh Jackman should have shot him at the barricade when he had a chance. But Britain's Guardian film critic complimented him on his low-key bleating in contrast to the coshing [bludgeoning] professionalism of the other stars. Crowe, who has angrily responded to criticism in the past, has been conspicuously silent in the face of the barrage of criticism. Oddly, it was the criticism directed at him by former American Idol winner Adam Lambert that provoked a response. Taking to Twitter, Lambert said over the weekend, I do think it was cool they were singing live -- but with that cast, they should have studio recorded and sweetened the vocals. What was needed, said Lambert, was a cast of singers who could act rather than actors who could sing. Surprisingly, Crowe did not disagree. When asked by a fan to comment on Lambert's remarks, Crowe tweeted: I don't disagree with Adam. Sure it could have been sweetened. [Director Tom] Hooper wanted it raw and real. That's how it is.
