Reese Witherspoon might have her day of reckoning at Paramount Pictures.

The actress is developing the dramatic thriller "The Reckoning" through her Type A Films shingle as a possible starring vehicle.

Based on a book by Jeff Long, the story centers on a photojournalist who arrives in Cambodia to cover the U.S. military search for the remains of an American pilot shot down during the Vietnam War.

Ted Tally ("Red Dragon," "The Silence of the Lambs") penned the screenplay, which is out to directors.

Witherspoon will produce the project along with Type A's Jennifer Simpson.

Paramount's Alli Shearmur and Michelle Raimo will oversee for the studio.

Long's book was published by Atria in July 2004.

Witherspoon is repped by Management 360 and attorney Steve Warren.
