It's no secret that Taylor Sheridan's Yellowstone empire has become something of a cultural phenomenon, and the latest prequel series 1923 is no different. Starring Harrison Ford and Helen Mirren as the leaders of the post-Great War Dutton clan, the series has been explosive from the get-go and promises just as spectacular an ending as the previous prequel series 1883. Narrated by Isabel May, the show tackles Great Depression-era issues in a Prohibition-era time, which makes sense when you consider that the Depression started a bit earlier in Montana.
