Paul Greengrass is attached to helm "The Tunnels". Based on Greg Mitchell's book proposal of the same name, the upcoming feature film will tell an untold true story drama about a great escape before the Berlin Wall fell in 1989, AceShowbiz said.

It focuses on a group of West Germans trying to get their loved ones out of East Berlin, with the unlikely help of American news networks funding their expedition. Mark Gordon ("Saving Private Ryan", "Source Code") serves as a producer.

Coming off his critically-acclaimed film "Captain Phillips", Greengrass is currently working on a new "Bourne" movie with the original actor Matt Damon. He is also eying "The Ballad of Richard Jewell" which is inspired by the real-life Atlanta Olympics bombing in 1996. Leonardo DiCaprio and Jonah Hill are cast to play the two key characters.
