The Pacific is a 2010 television series produced by HBO, Seven Network Australia, Sky Movies, Playtone and DreamWorks that premiered in the United States on 14 March 2010. The series is a companion piece to the 2001 miniseries Band of Brothers and focuses on the United States Marine Corps' actions in the Pacific Theater of Operations within the wider Pacific War. Whereas Band of Brothers followed one company of the 506th Parachute Infantry Regiment through the European Theater, The Pacific centers on the experiences of three Marines who were all in different regiments of the 1st Marine Division. The Pacific was spearheaded by Bruce McKenna, one of the main writers on Band of Brothers. Hugh Ambrose, the son of Band of Brothers author Stephen Ambrose, served as a project consultant. The miniseries features the 1st Marine Division's battles in the Pacific, such as Guadalcanal, Cape Gloucester, Peleliu, and Okinawa, as well as Basilone's involvement in the Battle of Iwo Jima. It 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 China Marine and Red Blood, Black Sand, the memoir of Chuck Tatum, a Marine who fought alongside Basilone on Iwo Jima.
