Developed by Universal, the biopic has been scripted by Josh Singer ('The Fifth Estate'), according to The Hollywood Reporter.
It is based on the book 'First Man: A Life of Neil A. Armstrong' written by James Hansen who had full access to Armstrong's family as well as NASA when he penned it.
The project has been developed for years. At one point, it was set up at Warner Bros with Clint Eastwood attached to direct and produce. No actor has been announced for the biopic.
