Gary Sinise played double amputee Vietnam War survivor Lt. Dan in the Oscar-winning drama “Forest Gump.” Eight years ago he formed a band of the same name, a band that has supported and performed for U.S. armed forces all over the world.

On July 4th, Sinise’s love of music and country can be seen in the new film “Lt. Dan Band: For the Common Good,” a documentary celebrating America’s heroes and chronicling the Academy Award-nominated actor’s band of patriots.

“I’m on the advisory board for the G.I. Film Festival in Washington, D.C . Five years ago we gave Gary our Spirit Award. That’s when he and I first started up a friendship,” the film’s director/producer, Jonathan Flora, told FOX411’s Pop Tarts column. “He found out I was a veteran of the 82nd airborne, and I started finding out about the things he does to support our troops. Of course I had no idea whatsoever, because he doesn’t do it for accolades or for self-promotion. I just remember being so inspired by his example of giving back that I wanted to share that inspiration.”

“Lt. Dan Band: For the Common Good” is being promoted with a unique, cause-driven marketing scheme designed to directly benefit the troops, and enable anyone and everyone to watch the film.

“The heart of this movie is really giving back to those who are willing to lay down their lives for this nation. Even the act of streaming the movie [which costs $3.99]. One out of every four dollars is going back to the Gary Sinise Foundation, so that he can continue doing what he’s doing,” Flora said, adding that Sinise’s foundation honors our nation’s defenders through an array of programs and projects, in addition to supporting several charities including the USO, Operation International Children and Snowball Express.
