Giving back to the military is in Vince Vaughn’s blood.

So when he was presented with the chance to treat troops at Edwards Air Force Base, California, to an advance screening of his upcoming film “Unfinished Business,” the three-time USO tour veteran had to say yes.

“I have military in my family,” Vaughn said. “My sister was [in the military], and [I have had] relatives [serve] way back, all the way back to the beginning, I believe, to the revolution.

“I’m always appreciative of the troops and all the sacrifices that are made and it’s always been important to me to express that.“

In addition to meeting with base leadership and personally kicking off the screening event, Vaughn got to chat and take photos with troops who had recently returned home and others who'd been recognized for excellence in their jobs.

“I hope that the movie brings them some laughter, that they have a good day laughing,” Vaughn said. “[I’m glad I] just get the chance to send the message that I know that a lot of people share, which is that they’re always in our minds and in our hearts.”

Vaughn traveled overseas with the USO to screen "Dodgeball: A True Underdog Story” for service members in Southwest Asia in 2004.

“I [had] shot ‘Dodgeball’ and was shooting 'Wedding Crashers,’” he said. “I had met Pat Tillman and then I got the news … on the TV that he had passed. It really bothered me and I had other friends who were overseas. So, I called the USO out of nowhere and said, ‘Can I come over?’”

The following year, Vaughn continued his USO relationship by screening "Wedding Crashers” for troops. In the past decade, he's entertained more than 8,735 servicemen and women through the USO.
