It's a bit tricky to give you a precise location because:
* Many locations were used: The filmmakers utilized various desert landscapes around the world to represent Tatooine's desolate beauty.
* Digital effects: A lot of the Tatooine scenes were created using CGI, so they weren't filmed on location at all.
Here are some of the real-world locations used for Tatooine shots:
* Tunisia: This was the primary location for the original trilogy. Places like Chott el Djerid, a salt lake, and the Erg Chebbi, a massive sand dune field, were featured prominently.
* Death Valley, California, USA: Used for some shots in the prequel trilogy.
* Mexico: The prequel trilogy also used locations in Mexico, but specific spots are less well-documented.
