The upcoming "World War Z" sequel is without a director after Juan Antonio Bayona backed out from the project over scheduling issues.

The project, led by Paramount and Plan B studios, is expected to continue moving toward an intended June 2017 release date, with Brad Pitt reprising his 2013 role as Gerry Lane.

"Bayona is no longer able to make 'World War Z 2' this year, and it is our ambition to do so," Paramount said in a statement to Deadline about the Spanish helmer.

"He is a wonderful director, and we hope to work with him soon."

Bayona's schedule is reportedly tied up by commitments associated with his latest project, "A Monster Calls," which is expected to release in mid-October.
