Pregnant actress Olivia Wilde has given herself two months to get back into shape after signing up to produce and star in a new psychological thriller following the birth of her first child.

The Tron: Legacy beauty is due to give birth on 4 May (14), and she is already making plans to get back to work.

Wilde has set her sights on returning to work this summer (14) after landing a leading role in Meadowland.

The subject matter will be an emotional one for the soon-to-be new mum - she will portray a mother whose son disappears.

Reed Morano will direct the project, which is expected to begin filming in New York in July (14), reports Deadline.com.
