Witherspoon to play astronaut in 'Pale Blue Dot'

Actress Reese Witherspoon has been roped in to produce and star in Fox Searchlight's upcoming film "Pale Blue Dot".

Written by Brian C. Brown and Elliott DiGuiseppi, the story of the film follows a successful female astronaut who, after coming back home from a mission in space, starts to unravel when confronted by her seemingly perfect US dream life, reports variety.com.

"Pale Blue Dot" explores the theory that astronauts who spend extended periods of time staring at the Earth from space will begin to lose their sense of reality once they return home.

Witherspoon will produce along with her producing partner Bruna Papandrea through their Pacific Standard production banner. Brown and DiGuiseppi will executive produce.
