Robert Downey Jr. and Reese Witherspoon are in talks to star in a thriller about alien invaders who keep traveling back in time and killing the human race, again and again.
At least, that's what I can glean from the official description of The Days Before, which Wanted helmer Timur Bekmambetov is also in talks to direct. According to Production Weekly (via Sci Fi Wire), the aliens travel back in time and wipe out humanity one day at a time, "yesterday by yesterday." Downey Jr.'s character keeps traveling back and trying to warn people that the end is coming, over and over again. It's not clear whom Witherspoon would play.
It sounds like a fun combination of Groundhog Day and that Star Trek: TNG episode where the Enterprise keeps blowing up. At the very least, with Bekmambetov involved, you know it'll look groovy.
