Despite the seemingly forgotten nature of Tarchia after the first decade or so of its known existence, that is to say after it was initially described, Tarchia managed to remain known enough that it was featured in a documentary in 2007. The IMAX movie Dinosaurs Alive! looked at the Triassic fauna of New Mexico and the Cretaceous fauna of Mongolia. The Mongolian desert scenes lean heavily on Tarbosaurus, but in its treks the large tyrannosaurid runs into a Tarchia. No hilarity ensues, but a short altercation does and it ends with Tarchia knocking Tarbosaurus off its feet and sending it into the sand.
