Paul Greengrass is directing a Berlin Wall drama The Tunnels.
The Tunnels is based on the true story a group of West Germans who are trying to get their loved ones out of East Berlin with the help of American news networks.
The story has been adapted for film from a book proposal by writer Greg Mitchell.
Mitchell revealed the news on his website, posting: "As my proposal for my next book The Tunnels was purchased by great upstart company FilmNation for [a] major film directed by my one of my film heroes Paul Greengrass.
"Quite flattered by interest over [the] past 10 days from several leading studios and A-list directors but very happy to be with Greengrass – I was one of [the] early fans of his Bloody Sunday back in 2002.
"Amazing story and now opportunity on the page and on the screen."
