The development comes after Jim Gianopulos joined as the new CEO of the Paramount Pictures, reported Variety.
While Gianopulos has not officially greenlit the movie yet, he is expected to do so in the coming weeks.
According to the sources production would probably begin in the first quarter of 2018.
If the deal is finalised, it would mark a big milestone in the long development process that started last summer. Pitt met with a handful of directors but nothing materialised until he decided to reach out to Fincher.
