Robert Pattinson's Cosmopolis wife cast

Robert Pattinson's wife in new movie 'Cosmopolis' will be played by Canadian actress Sarah Gadon.

'A Dangerous Method' actress Sarah will play the British hunk's estranged spouse in the film about a businessman who bets all of his money only to find himself at the centre of an assassination plot.

Samantha Morton, Paul Giamatti and Juliette Binoche have also been cast in the project, which will be directed by David Cronenberg.

Keira Knightley was initially rumoured for the role but negotiations eventually came to a halt.

Sarah is best known for her TV roles, having recently starred in 'The Border' and 'Happy Town'.

However in 2010 she made a leap into cinema, with parts in 'The Moth Diaries', 'A Dangerous Method' and 'Dream House'.

'Cosmopolis' will be the second time she has worked with Cronenberg.

The movie will be Robert's first project since he completed filming on the 'Twilight Saga' franchise, and he will next be seen in romantic drama 'Water For Elephants' with Reese Witherspoon.
