A companion series to HBO's acclaimed miniseries Band of Brothers, 2010's The Pacific cast brings to life the real people who participated in the harrowing World War II experiences depicted in the show. Set over the same few years as Band of Brothers, The Pacific focuses on United States Marines fighting the Japanese military forces on the island battlefields of the Pacific Ocean. The more grim and violent series shows the loss of humanity and hope in these soldiers as their enemy refuses to surrender, and the battles become more brutal.
