Bayona has been set to direct the sequel for Paramount, but when he was eyed to direct the "Jurassic World" sequel for Universal, has involvement in "World War Z" was left in question.

2013's original "World War Z" film was based on a novel by author Max Brooks, adapted by writers Matthew Michael Carnahan, Drew Goddard and Damon Lindelof. Brad Pitt is set to return in the lead role and as producer.

"World War Z 2" is slated to debut in theaters on June 9, 2017.
