Pierce Brosnan has signed on to lead an adaptation of Stuart Neville's The Twelve (titled Ghosts of Belfast in America), says a story at The Hollywood Reporter. The film version will be titled Last Man Out and has been scripted by Craig Ferguson and Ted Mulkerin. Published last year, Neville's novel is officially described as follows:

Former paramilitary killer Gerry Fegan is haunted by his victims, twelve souls who shadow his every waking day and scream through every drunken night. Just as he reaches the edge of sanity they reveal their desire: vengeance on those who engineered their deaths. From the greedy politicians to the corrupt security forces, the street thugs to the complacent bystanders who let it happen, all must pay the price.

When Fegan's vendetta threatens to derail Northern Ireland's peace process and destabilise its fledgling government, old comrades and enemies alike want him gone. David Campbell, a double agent lost between the forces of law and terror, takes the job. But he has his own reasons for eliminating Fegan; the secrets of a dirty war should stay buried, even if its ghosts do not.

Set against the backdrop of a post-conflict Northern Ireland struggling with its past, "The Twelve" takes the reader from the back streets of Belfast, where violence and politics go hand-in-hand, to the country's darkest heart.

Terry Loan will direct with Beau St. Clair, Steve Clark-Hall, Jonathan Loughran and Rebecca Tucker producing.
