When I watched Galaxy Quest in the theater, I noticed how a couple of the creatures reminded me of Athasian monsters. Later, watching Star Wars: The Phantom Menace, I was struck by how much like Athas Tatooine was. For years since, I have wanted to make a video for my Dark Sun players of these iconic scenes. Well, here it is.
At some point, I hope to revise and expand this with scenes from other movies, nature documentaries, etc. In the meantime, take a look at this, ignore the technology and aliens, and enjoy these views of terrain and creatures from Athas. Hopefully this will give you a better picture of what various parts of Athas look like.
