In January 2016, “World War Z 2” lost director Juan Antonio Bayona, who was said to be held up finishing post-production on “A Monster Calls.”

The search has been on for a replacement ever since, with Pitt himself imploring some of Hollywood’s biggest directors to step in and help the franchise, numerous individuals have told TheWrap throughout the process.

The first “World War Z” movie also had its share of behind-the-scenes strife, as script doctors Damon Lindelof and Drew Goddard boarded the project late in the game to f ix its third act. The film went on to gross nearly $540 million worldwide, opening the door for a sequel.

As for “Friday the 13th,” initial news about the project angled for a younger take on undead serial killer Jason Voorhees. No casting emerged, and in August a lawsuit hit from the writer of the 1980 classic. It’s unclear how that litigation might have affected Paramount’s development on the project.

It’s not all uncertainty from the studio: It’s safe to say that “mother!” finds itself slotted for awards season thanks to its mid-October rollout.
