Yellowstone National Park will reintroduce a group of characters from 1923 to represent the era of the park's establishment in 1944. The historic characters, including park superintendent Horace M. Albright and ranger Harvey R. Minnick, will be portrayed by new actors to educate and entertain visitors. Their stories will shed light on the challenges faced during the park's early years and offer a unique way to experience Yellowstone's history. The re-casting aims to provide a more immersive and engaging experience for park visitors.
