From the producers of Band of Brothers, The Pacific tracks the real-life journeys of three U.S. Marines–Robert Leckie (James Badge Dale), Eugene Sledge (Joe Mazzello) and John Basilone (Jon Seda) who were all in different regiments (1st, 5th, and 7th, respectively) of the 1st Marine Division. The extraordinary experiences of these men and their fellow Marines take them from the first clash with the Japanese in the haunted jungles of Guadalcanal, through the impenetrable rain forests of Cape Gloucester, across the blasted coral strongholds of Peleliu, up the black sand terraces of Iwo Jima, through the killing fields of Okinawa, to the triumphant, yet uneasy, return home after V-J Day. The Pacific is based primarily on the memoirs of two U.S. Marines: With the Old Breed: At Peleliu and Okinawa by Eugene Sledge and Helmet for My Pillow by Robert Leckie. It also draws on Sledge’s memoir China Marine and Red Blood, Black Sand, the memoir of Chuck Tatum, a Marine who fought alongside Basilone on Iwo Jima.
