The 'Suicide Squad' actress' production company LuckyChap Entertainment have agreed to adapt the novel by Gin Phillips for Warner Bros and Robbie will take on the lead role of Joan, according to the Hollywood reporter.

The book is due for release in May 2017 and a summary on Phillips' website teases the story of Joan and her four-year-old son, who are trapped in a zoo with a gunman on the loose.

Di Novi Pictures' Denise Di Novi and Alison Greenspan will co-produce and a director and screenwriter are yet to be found.

Meanwhile, Robbie will start filming 'I, Tonya,' next year and is also set to produce and play the lead role in biopic.

And last month it was reported the 26-year-old actress is in the final stages of talks to star in Sony's live-action and computer generated hybrid production 'Peter Rabbit'.

The adaptation of the children's tale penned by Beatrix Potter already boasts James Corden, Rose Byrne, Daisy Ridley, Domhnall Gleeson, and Elizabeth Debicki.

The film is scheduled for release in April 2018 and coincides with the 150th anniversary of the birth of author-and-illustrator Potter - who died in 1943 at the age of 77.
