Robbie, 26, will produce along with Di Novi and Alison Greenspan, but it is uncertain if she will also star in the project, reported Variety.
Gin Phillips' book, sold last month to Viking, centers on a mother and her son trapped in a zoo with a gunman on the loose.
The deal comes two months after Robbie signed a first-look deal with Warner Bros. To develop and produce feature films through her LuckyChap Entertainment production company.
