Taylor Sheridan revealed why HBO rejected "Yellowstone". 

In a recent interview with The Hollywood Reporter, the show's creator, Taylor Sheridan,  

was frank about the beginning of the television program Yellowstone. 

Sheridan asserted that Yellowstone hardly ever saw the light of day because of the skepticism of an unnamed HBO executive.

Sheridan eventually approached HBO with the idea of turning Yellowstone into a TV show. 

Yellowstone was originally intended to be a movie. Former HBO executive Michael Lombardo loved the idea back then. 

Lombardo said of the show, "I thought Taylor was the real deal," when asked about it. 

In a world where people pose, he was writing what he knew and deeply cared about the show. 

The idea of performing a modern-classic Western was a good one because we were always performing urban shows.
