Three of the biggest stars in America are lending their voices to Joining Forces, the initiative started by First Lady Michelle Obama and Dr.Jill Biden to bring attention to the unique needs and strength of America's military families.

Tom Hanks, Oprah Winfrey and Steven Spielberg have each created public service announcements (PSAs) that tell real stories about America's military families and call on all Americans to give back to ensure service members and military families have the support they have earned.

"The entertainment community answered the Joining Forces call and has done what they do best -- bring to life stories that move us," said Mrs. Obama. "Through this PSA campaign, Americans will learn more about the unique challenges and needs of our military families, see their strength, resilience and service, and find out how they can give back to these extraordinary troops and families who have given us so much."

The project was conceived by Academy Award-winning producer Bruce Cohen, who leads the Inter-Guild Joining Forces Task Force, an entertainment industry coalitionthat provides creative and production support for Joining Forces. Each of the PSAs tells the story of a military familyas they endure the hardship of a deployment overseas. The PSAs will be airing on A&E, CBS, NBC, ABC, FOX, and WB networks.

Dr. Biden, whose son served in Iraq, said, "As a military mom, I know just how much it means when people reach out to show their support for our service members and their families. The first lady and I hope that this campaign will inspire more Americans to take action and reach out to military families in their own communities around the country."
