Burton recruits Witherspoon and Reynolds for 'antihero' biopic

Reese Witherspoon and Ryan Reynolds are set to star in 'Big Eyes'.

The pair have signed up to play artists Margaret and Walter Keane - who became famous in the 1950s and 60s after their paintings of large-eyed kids were one of the first mass marketed art sensations at the time - in a film that will be produced by Tim Burton.
