I'm surprised no one has talked yet about the way the songs were filmed, with the actual singing performances being done on set, in costume instead of in the studio beforehand- http://www.youtube.com/watch?v=0cDVdg7gVdg
Well, Hathaway's absolutely heart-rending rendition of "I'm So Damn Sad," done entirely in one long closeup, would have been impossible to match if she'd been lipsynching.
On the other hand, Crowe might have benefited from a few more takes to get that perfect sound in the studio.
