Robert Downey Jr could be set to star as a paranoid survivalist in a remake of Emergency! This Book Will Save Your Life.
According to Deadline, Sony Pictures Entertainment has obtained rights to make a movie version of the Neil Strauss non-fiction book.
Robert and his wife Susan Downey - the producer of Sherlock Holmes - are expected to produce with The Love Guru's Michael De Luca.
Allan Loeb, who penned Wall Street: Money Never Sleeps, will write the film as a potential star vehicle for Robert, according to the website.
The book tells how the author, convinced about a forthcoming apocalypse, moved his family and taught himself how to live off the land.
