Warner Bros has acquired the film rights to "Heaven's Shadow", a science fiction trilogy by David Goyer and Michael Cassutt.
The trilogy begins when an object is discovered heading for earth. Initial panic gives way to a competition between governments to be first to intercept what they believe is a breakaway meteor. What the astronauts discover leads to an encounter with alien forces that are a threat to humanity.
Goyer will also produce through his Phantom Four banner.
