The War of the Worlds. We've had modern adaptations and the BBC series which was so annoyingly close to the right track but veered off it script-wise (sometimes for budgetary reasons I assume) but never a truly faithful adaptation of one of the landmark books of science fiction. Just once I want to see the British army of the Victorian period being given a beating by the Martians, Thunderchild steaming in to take on the tripods etc etc. The material is so good so why has it never been done?
