Theater icon, award-winning film and television star, and American patriot Gary Sinise shares the never-before-told story of his journey from trouble-making Chicago kid to cofounder of the legendary Steppenwolf Theater Company, world-famous actor, and tireless advocate for America's active duty defenders, veterans, and first responders.As a kid in suburban Chicago, Gary Sinise was more interested in sports and rock-n-roll than reading or schoolwork. But when he impulsively auditioned for a school production of "West Side Story," he found his purpose--or so it seemed. Within a few years Gary and a handful of friends created what became one of the most exciting and important new theater companies in America. From its home in a church basement in Chicago, the Steppenwolf Theatre launched a series of groundbreaking productions, igniting Gary's career along with those of John Malkovich, Joan Allen, Gary Cole, Laurie Metcalf, Dennis Farina, John Mahoney, and others. Television and film came calling soon after, and Gary starred in Of Mice and Men (which he directed) and The Stand before taking the role that would change his life in unforeseeable ways: Lieutenant Dan in the Academy Award-winning Forrest Gump. The military community's embrace of the character of the disabled veteran was matched only by the depth of Gary's realization that America's defenders had not received all the honor, respect, and gratitude their sacrifices deserve. In the aftermath of the September 11 attacks, this became Gary's mission. While starring in hits like Apollo 13, Ransom, Truman, George Wallace, CSY: NY, and Criminal Minds: Beyond Borders, Gary has worked tirelessly on behalf of those who serve this country, entertaining more than a half million troops around the world playing bass guitar with his Lieutenant Dan Band, raising funds on behalf of veterans, and eventually founding the Gary Sinise Foundation with a mission to serve and honor America's defenders, veterans, first responders, their families, and those in need.Grateful American is the moving, entertaining, profoundly gripping story of how one man found his calling: to see that those who defend this country and its freedoms are never forgotten.
