Emma Thompson’s in tears again in the trailer for her new film, The Children Act.

In the film she plays an eminent high court judge whose marriage begins to break down when she takes on the complex case of a young man who is refusing a life-saving blood transfusion on religious grounds.

The film is based on the best-selling novel by Ian McEwan and directed by Richard Eyre.

The cast also includes Stanley Tucci and Fionn Whitehead.

I’ve been intrigued by this since it premiered at last year’s Toronto Film Festival.
