Ted Thin Elk, a renowned Sicangu Lakota, spent the majority of his life on the esteemed Rosebud Sioux Indian Reservation in South Dakota, where he was deeply rooted in the local culture and community. Despite his relatively limited exposure to the world of cinema, Thin Elk's life took an unexpected turn when he landed his first acting role at the ripe age of 72, playing the part of "Grandpa Samuel Reaches" in the 1992 film Thunderheart.
Contrary to his rugged and rebellious reputation, Val Kilmer, his co-star and a Hollywood heavyweight, treated the septuagenarian first-time actor with utmost respect and deference, offering guidance and support throughout the filming process. When the cameras weren't rolling, the two could often be found engaging in lively discussions about Native American topics, with a particular focus on Lakota culture and history.
Ted Thin Elk's impressive credentials extend far beyond his brief but notable foray into the world of acting. In 1992, he was honored with a "First Americans in the Arts" award, marking the first year the prestigious honor was bestowed. As a highly respected elder on the Rosebud Reservation, Thin Elk was a valued member of the Sicangu Treaty Council and the Grey Eagle Society, two esteemed organizations dedicated to preserving and promoting the cultural heritage of the Lakota people.
