FORT WORTH, Texas — Fort Worth resident Barry Corbin is most comfortable in his yard, in his cowboy hat, enjoying an evening and wife with his two dogs.
"This one's about to bud," he noted, checking out the budding trees on his lawn.
But this low-key born and bred Texan also knows a thing or two about Hollywood.
"I guess I’ve been acting about 80 years," Corbin told WFAA from inside his home.
Corbin has collected movie credits in some big movies, like "Urban Cowboy" and "No Country for Old Men," just to name a few. Most recently, the Cowtown native hit the big screen with the supporting role of an undertaker in the hit western crime saga, "Killers of the Flower Moon."
"It’s the history of our country," Corbin said of the movie. "Part of the history of our country."
"Killers of the Flower Moon" is based on a true and dark story. The film chronicles the real-life 1920s murders of members of the Osage Nation, who were mysteriously killed off after becoming some of the richest people in the world for discovering oil underneath their land; a deeply painful story of white men who murdered Native Americans to steal their money.
And Corbin isn't the film's only Fort Worth connection.
The movie is based off a book, written by Journalist David Gann. To write that book, Gann pulled records from the National Archives at Fort Worth to investigate the murders.
"The book uses archives that we stored here," Michael Wright, Director of Archival Operations at the National Archives at Fort Worth, told WFAA.
"These are the primary sources, this is what actually happened," he said.
Gann reviewed dozens of archives, including original handwritten letters and financial records from real-life victims to piece together the history of what happened.
"Transcripts of what was said in court, lists of witnesses," said NARA Archivist Jenny McMillen Sweeny.
McMillen said they also sent copies of those records housed here in North Texas to director Martin Scorsese's researchers to help him write the movie’s screenplay.
Corbin said he's glad the movie was made to shed light on the important but often untold story about the murders.
"Now, at least, the communication is open, which I think is a good thing," he said.
