They will play Talia al Ghul and Roman Sionis respectively.

On casting Cotillard, Director Christopher Nolan stated, “I am delighted to have the opportunity to work with Marion again and have no doubt she will be a great addition to our ensemble cast and bring to life a key part of the universe we have created as we finish our story.” On the addition of Joseph Gordon-Levitt, Nolan said, “I am thrilled to be working with Joseph again after a delightful experience working with him on Inception and am certain he will deliver another thrilling performance as one of Batman’s most popular villains.”

Nolan will direct the film from a screenplay he wrote with Jonathan Nolan, from a story by Christopher Nolan and David S. Goyer. Nolan will also produce the film with his longtime producing partner, Emma Thomas, and Charles Roven.
