Video: 'American Sniper' Star Bradley Cooper Speaks to Texas Audience — Including Glenn Beck — Before Movie Premiere

Actor Bradley Cooper traveled to Plano, Texas, to attend the "American Sniper" movie premiere at Cinemark West Plano alongside Chris Kyle's widow, Taya Kyle, and others on Wednesday night.

"I just want to say thank you -- what an honor it is to be here," Cooper said. "All we tried to do was just tell Chris' story and be as truthful as we possibly could. And we thought that if we got one nugget of his truth, one nugget of his real life and the relationship that they had, that maybe people could watch this movie and relate to it."

He also spoke about bringing attention to the "plight" of America's military veterans and said he hopes the film might make people think twice about trying to help.

Glenn Beck, who also attended the premiere, uploaded video of Cooper speaking to the audience before the screening:

Taya Kyle also said a prayer before the movie premiere. Beck uploaded part of it on Facebook as well:

The movie, "American Sniper," is based on Chris Kyle's 2012 memoir that recounts his journey from being a rodeo cowboy to a trained sniper credited with 160 kills. He was honorably discharged in 2009 after 10 years of service, including four tours in Iraq.

Taya Kyle told The Dallas Morning News recently that Cooper did an excellent job accurately portraying her husband and the difficult decisions he faced while fighting in Iraq and his struggles with determining his role when he returned from war.

In February 2013, Kyle and his friend, Chad Littlefield, were killed at a shooting range. Ex-Marine Eddie Ray Routh is charged with capital murder, and authorities say he confessed to the killings to a Texas Ranger. He remains in jail in lieu of $3 million bail. His trial is scheduled to start next month.

Cooper and the film's director, Clint Eastwood, visited Taya Kyle in Midlothian - about 25 miles south of Dallas - before filming. The trio sat around and talked, with Kyle showing them her husband's baseball caps, cowboy boots and the clothes still hanging in his closet
