In Isaac Asimov’s The End of Eternity, a group of people, known as the Eternals, living outside of space-time travel throughout history making tiny Reality Changes in an effort to improve conditions for mankind throughout time. When one of them falls in love with a woman in the past and learns that she will cease to exist with the next Reality Change, he breaks all the rules to save her.

That’s the bare bones outline of the story. If you want to know more read the book, or go see Kevin Macdonald’s adaptation of it. The director has just signed on to his first science fiction project, and will be writing and directing The End of Eternity for New Regency.

You know Macdonald from some great docs – including the should-be-included-with-the-DVD-of-Munich film One Day In September - and The Last King of Scotland and the currently in theaters State of Play. The End of Eternity won’t be Macdonald’s next film – he’s working on the Roman mystery thriller Eagle of the Ninth with Channing Tatum and Jamie Bell – but this scifi story could be after that.
