My problem is that Rosie O'Donnell nearly always plays Rosie O'Donnell -- I can see her getting some easy laughs as Mme. Thenardier, but I can't imagine her actually creating the illusion that she's a rural French inn-keeper. She'd far more likely seem like Rosie O'Donnell deposited by time machine and bad luck in the village of Montfermeil in 1823.

Sharing your supper, sharing your bed /
Simple joys have a simple voice:
It says why not go ahead?"
