Reel Fanatic blogger Keith Demko pointed out some news from the French site CinEmpire: Cuarón’s next road movie, A Boy and His Shoe, may feature French actors Daniel Auteuil and Charlotte Gainsbourg (yet to be announced officially).

[Edit] Reports indicate that auditions for the role of the French girl are now complete, while casting for the Scottish boys is now ongoing. Casting calls have gone out in the south of France. It appears that the search for a French girl “in the style of Charlotte Gainsbourg” is still going on. Thanks to lala for the tip. Details here and here (in French).
