Sal (2010)

Thought this might interest you guys, not really going to be a Western but the plot is about a film director who wants to make a Western! A trailer is in order and it uses SW music!

IMDb Plot Summary: A film director obsessed with making a western decides to go to Northern Chile in search of a story for his screenplay. Being confused with another, a real adventure begins. Now he will have a good script… If he leaves alive The story of a man with no history. The journey of an author becoming his own character and his impossible return.

Sounds eerily similar to 2001 with HAL
