Samuel L. Jackson has joined Sebastian Stan, Christopher Plummer, William Hurt, Bradley Whitford, Michael Imperioli, Linus Roache, John Savage and Diane Ladd in writer/director Todd Robinson’s political drama The Last Full Measure. Principal Photography begins in Atlanta and Costa Rica later this month.

Based on the true story of a present-day cover-up investigation, the film follows young Pentagon investigator Scott Huffman (Stan) battling the political machine in Washington. He reluctantly teams with veterans of Operation Abilene to convince Congress to award the Medal of Honor to a courageous Air Force medic, William Pitsenbarger, who is seen saving the lives of over 60 Marines ambushed in one of the bloodiest battles of the Vietnam war. As the battle waged on, and after the last helicopter left, he saved lives until his own was sacrificed.

Steyn are executive producing. Pen Densham and John Watson are co-executive producers.
