Pre-production on Roland Emmerich’s near-future sci-fi blockbuster Singularity has been put on hold to give the Day After Tomorrow/Independence Day writer-director more time to revise the script with his 2012 cowriter Harald Kloser and Ray Kurzweil, a rep for Sony Pictures confirms with EW. Kurzweil is the man who coined the titular artificial intelligence term, who’ll now join the team for revisions. (The news was first reported by Variety.)

The film is expected to stay on target for a May 2013 release. Per the trade, the film centers on a nanotechnology expert who uses a new procedure to save his son, Adam, whose consciousness is transferred into nanobots that take his physical form.
