该节目把第一次世界大战和第二次世界大战「串联起来」，描述了1914年到1945年一条完整的时间线上的故事（一战时罗斯福、希特勒、佩顿、墨索里尼、斯大林、丘吉尔等人还只是30岁左右的年轻人，二战时已变成风云人物）。历史频道自称这是「同类节目中首创的叙事手法」。
　　The World Wars tells the story of three decades of war told through the eyes of various men who were its key players: Roosevelt, Hitler, Patton, Mussolini, Churchill, Tojo, DeGaulle and MacArthur. The series examines the two wars as one contiguous timeline starting in 1914 and concluding in 1945 with these unique individuals coming of age in World War I before ultimately calling the shots in World War II.
