The "World War Z" sequel's script undergoes yet another rewrite.

According to THR, the follow up will now be written by Dennis Kelly, the creator of the British television series "Utopia."

The movie will be directed by J.A. Bayona (The Impossible), to be co-produced by Skydance Productions, with studio executive David Ellison joining Jeremy Kleiner, Ian Bryce, Dede Gardner and Brad Pitt as the movie's producers.

The "World War Z" sequel's previous writer, Steven Knight, turned in the initial draft of the script back in August. Knight elaborated on what he liked about the first installment which could hint at what can be expected from the sequel.

"I think the beauty of the first film was the way that it never paused for breath," he told Collider. "It never spent a moment thinking, 'Hang on a minute, we'd better tell the audience what this is all about.' It stayed in the moment, it stayed with that person."

The first movie was directed Marc Foster and was written by Drew Goddard (The Martian), Damon Lindelof (Prometheus) abd Matthew Michael Carnahan. Production was plagued with extensive reshoots and a "reworking" of the film's third act.

The original third act saw Brad Pitt's character "leading team of zombie-clearers in Russia, discovering that cold was their weakness, then setting out to rescue his wife from the clutches of Matthew Fox's military character in the planned follow-up." 

The movie launched in 2013 and went on to be a box office success, earning $540 million globally. It is currently the highest grossing zombie movie. 

"World War Z" starred Brad Pitt (Fight Club, Fury), Mireille Enos (If I Stay, Sabotage), James Badge Dale (Iron Man 3, The Grey), Matthew Fox (Lost, Vantage Point) and David Morse (Disturbia, The Hurt Locker).

Release date of "World War Z" Sequel is on June 9, 2017.
