Downey, Witherspoon Count “Days Before”

Robert Downey Jr, Reese Witherspoon, and “Wanted” director Timur Bekmambetov are in talks for Warner Bros’ sci-fi epic “The Days Before” according to Production Weekly.

Chad St. John’s script follows a race of aliens who invade Earth by traveling backwards through time and wiping out humanity, one day at a time, yesterday by yesterday.

One man attempts to stay “a yesterday ahead of them”, and every time he must try to convince the world that “the end is coming”, again.

Gianni Nunnari (“300”) will produce.
