The 1,000-page books revolves around Jake Epping, a 35-year-old high school English teacher from Maine who travels back in time -- to 1958 -- and starts another life in preparation for his attempt to prevent the Kennedy assassination.
According to Variety, the project has yet to land a distributor, though Demme wants to begin shooting in fall 2012. Demme should have no problem raising funds: He's done well with pop novels, from Thomas Harris' 'The Silence of the Lambs' through Richard Condon's 'The Manchurian Candidate.'
Time travel to save assassinated presidents has long been a staple of science fiction TV and film, with the most notable being the 1961 episode of 'Twilight Zone,' 'Back There,' in which a man goes back in time to prevent the assassination of President Lincoln. A 1990 telefilm, 'Running Against Time,' and a 2000 feature, 'Timequest,' both revolved around attempts to change history by preventing the Kennedy murder.
It will be interesting to see how King handles the time travel quandaries (we suspect most of the book will concern life in the late 1950s) -- and Demme handles the book -- but without a time machine, we'll just have to wait until -- well, 2013.
