The Unhappy Wife and the Shopgirl

It was bound to happen: Cate Blanchett and Mia Wasikowska will have an affair.

Cue up the obvious: For the screen.

The two actress – both tops of each of their generations, IMHO – are set to co-star in an adaptation of the Patricia Highsmith novel Carol that Todd Haynes is directing.

The film will revolve around the relationship between two 1920s women: the unhappy, estranged wife of a rich man and a department store shopgirl dreaming of a more fulfilling life.

Haynes is expected to roll cameras in London and New York in October.
