American Sniper' Chris Kyle's Dad Looked Two Hollywood Megastars in the Eye and Gave Them One Crystal-Clear Warning About His Son

The father of Navy SEAL Chris Kyle reportedly warned actors Bradley Cooper and Clint Eastwood that there would be hell to pay if they did “anything” to disrespect his son in their Hollywood production of “American Sniper,” which is based on Kyle’s autobiography of the same name.

Eastwood directed the film and Cooper portrays Kyle, considered to be the most deadly sniper in American history. Both Hollywood stars reportedly traveled to Hamilton, Texas, to discuss the film with Wayne Kyle, the late SEAL’s father.

Wayne told Eastwood he wasn’t happy that a movie was being made about his son, but his biggest concern was ensuring the truth was told.

“They both looked me in the eye and told me they would not do anything to harm my son's reputation,” Wayne told MailOnline.

Then he warned both men. “I told them I would unleash hell on them if they did anything to disrespect my son,” he added.

Wayne Kyle said he ended up liking both men and praised the duo for traveling all the way to Texas to consult him about the movie.

Kyle was tragically killed in 2013 when he and a fellow veteran, Chad Littlefield, were fatally shot by Eddie Ray Routh at a remote gun range in Glen Rose, Texas. Kyle's father said he’s unable to express his real thoughts about his son’s alleged killer due to the upcoming murder trial.

“All I will say is that PTSD is not an excuse for murder,” he said. “I will be at the murder trial with my wife Deby.”
