Thumbs way, way up. She's one of the best actresses going today, and she's strikingly gorgeous. She's the kind of actress who can come off as sensual without really trying, and, yes, at least part of that has to do with her accent.
Her talent is the most attractive thing about her to me though. She definitely deserved an Oscar for "La Vie En Rose." She gave a stunning performance as Edith Piaf.
