Fans of director Steven Spielberg who were looking forward to the director's return to the sci-fi genre with Robopocalypse will have to wait even longer. The 20th Century Fox and DreamWorks co-production has been indefinitely delayed. The project was initially set for an April 25, 2014 release date. Here's what the director's spokesperson, Marvin Levy, had to say in a statement.

"(It is) too important and the script is not ready, and it's too expensive to produce. It's back to the drawing board to see what is possible."

The screenplay adaptation of Daniel H. Wilson's sci-fi novel was written by Drew Goddard (The Cabin in the Woods). It isn't known if the studios are seeking new writers. Chris Hemsworth was in talks for the male lead, while Anne Hathaway and Ben Whishaw were circling the project as well. The story is set in the aftermath of a robotic uprising, focusing on how humanity has adapted after the machines took over.

The project was slated to be Steven Spielberg's next movie after Lincoln. It isn't known which of the director's many projects he will tackle next, now that this has faltered.
