With Hollywood fresh out of ideas for tentpole films in the sci-fi genre (the franchise re-boot of Star Trek is a see case in point) the people that run the Isaac Asimov estate seeing plenty of golden ops to bring the grandfather of sci-fi writing into the feature film realm. After former new line execs Bob Shaye and Michael Lynne winning bid for Foundation, now New Regency is looking to manipulate the future by bringing helmer Kevin MacDonald on board after he completes his next project (Eagle of the Ninth) for Focus Features. The rights for The End of Eternity were floating around Hollywood a bit earlier in the decade, and it would suit a 20th Century Fox as a summer pic down the line.
The Asimov novel is a futuristic tale in which humanity is controlled by a ruling class called Eternity, member of which can manipulate time to alter history and prevent disasters or wipe out undesirables. One of the time cops flirts with disaster when he breaks the cardinal Eternity rule and falls in love with a woman from another time period. As long as 20th Century learned from the Jumper disaster, then we are okay.
