What is Casting Couch? It’s a round-up of Hollywood casting news, not one of those porn videos where a 19-year-old gets exploited in a grimy-looking office. Move along, perv. Now that we’ve got all of those live action Snow White movies out of the way, it makes sense that we would move down the fairy tale lineup and start seeing a rash of new Cinderella projects popping up. And, if Disney has their way, their Mark Romanek-directed Cinderella script from The Devil Wears Prada scribe Aline Brosh McKenna will be the hit that starts the trend. They’re trying to get casting for the film off on the right foot with the acquisition of a big name, as Deadline reports that the House of Mouse is in serious negotiations with Cate Blanchett to come on board to play a character called Lady Tremaine, known in some circles as the wicked stepmother. Given her experience playing a creepy elf in the Lord of the Rings movies, this seems like something of a perfect fit.
