Win one of 10 copies of the Space Odyssey book

TODO alt text

Celebrating its 50th anniversary this year, 2001: A Space Odyssey stands as one of the greatest science fiction movies ever made. Still dazzling, still provocative, still as profoundly intriguing as its enigmatic black monolith, this collaboration between the talents of Stanley Kubrick and Arthur C Clarke retains all its otherworldly power.

Space Odyssey by Michael Benson is a new book that explores the making of this screen masterpiece. Exhaustively researched and featuring many previously unseen photographs, it's the definitive account of the film's creation, from ape to starchild. Tom Hanks calls it "dense, intense, detailed and authoritative" - and you wouldn't argue with that nice Mr Hanks, now would you?
