Director Michael Bay has been tapped to helm the film adaptation of Robopocalypse, the 2011 best-selling sci-fi novel by Daniel H. Wilson.

According to The Hollywood Reporter, Bay is set to take over the directorial reins from Steven Spielberg, who originally planned on helming the adaptation as far back as 2010, prior even to the release of the novel. Spielberg will reportedly continue on as a producer on the film, which had been on hold since 2014.

Humans and freeborn robots wage war against Archos R-14 and the legion of robots under its control.

Production on Robopocalyse will not start until after Bay has completed his next project, 6 Underground, which is expected to release in the summer of 2019.
