It is a day of disappointment for fans waiting on the progress of “World War Z 2” because the film just encountered a major setback.

Cinema Blend reports that director Juan Antonio Bayona just left the much-awaited sequel to the 2013 zombie apocalypse hit.

According to the website, the reason behind Bayona’s decision to leave the project stems from the need to fulfill his other responsibilities. In this case, the director is attached to wrap the film “A Monster Calls” which is a big screen adaptation of the novel by Patrick Ness. The film stars Felicity Jones, Liam Neeson, and Sigourney Weaver.

Paramount, the studio behind “World War Z 2”, released an official statement about the director’s exit.

Screen Rant relays the announcement as follows:

“Bayona is no longer able to make World War Z 2 this year, and it is our ambition to do so. He is a wonderful director and we hope to work with him soon.”

However, Screen Rant details that Bayona’s attachment to “A Monster Calls” may not be his only reason for leaving “World War Z 2”. Instead, the website points out that the director is also one of the few considered to helm the sequel to “Jurassic World”.

Although Bayona’s involvement with the Chris Pratt-starrer remains a rumor for now, the website relays that Bayona was indeed being eyed for the project last year; therefore, it is not far-fetched that he is being considered as a candidate again.

For now, Paramount is dedicated to stick with its plan to release “World War Z 2” on the schedule premiere date — June 9, 2017. If the studio would want to release the project on time, then it should not take long for them to hire a replacement for Bayona who can take on the sequel as soon as possible.

The first film’s lead, Brad Pitt, is set to return for “World War Z 2”.
