Syfy has ordered Arthur C. Clarke’s classic novel “Childhood’s End” as a six-hour miniseries slated for 2015.

The novel will be adapted for the screen by Matthew Graham, creator of BBC’s “Life on Mars” and “Ashes to Ashes,” with Universal Cable Productions as the studio. Akiva Goldsman and Mike De Luca are attached as executive producers.

Nick Hurran, recent Emmy nominee for “Sherlock: His Last Vow,” will direct. Neville Kidd and Yan Miles, Emmy winners for “Sherlock: His Last Vow” are also set as director of photography and editor, respectively.

Originally published in 1953, “Childhood’s End” follows the peaceful alien invasion of earth by the mysterious Overlords, whose arrival begins decades of apparent utopia under indirect alien rule, at the cost of human identity and culture.

“As we aggressively develop scripted programming over a diverse creative landscape, we want our content to reflect the greatest sci-fi stories from the past and the present,” said Dave Howe, president of Syfy. “The powerful themes of ‘Childhood’s End,’ from the fearsome price of peace and prosperity, to the very question of what constitutes a human being, remain fascinating and timeless. This will be the most ambitious project for Syfy in many years.”

Graham is also developing the BBC America paranormal drama “The Living and the Dead” with his “Mars” and “Ashes” co-creator Ashley Pharoah.
