Tom Hanks and Michael Douglas are among the famous faces lending their star power to a new scheme to support war veterans.
Alec Baldwin and Sarah Jessica Parker have also signed up to film a series of public service announcements (PSA) as part of the Got Your 6 initiative, which aims to provide help to soldiers and their families after they return from war.
A number of major movie studios and American TV networks are also backing the scheme, inspired by U.S. First Lady Michelle Obama's Joining Forces campaign.
She says in a statement, "The entertainment industry captures our imaginations, opens our eyes and touches our hearts, and I'm proud to work with them on our Joining Forces initiative.
"By sharing the stories of strength and resilience that define our military families, we can motivate evenmore Americans to honor these courageous individuals in new ways".
Universal Studios chief Ron Meyer adds, "It's an opportunity for all ofus. I can't think of anything more important than supporting the troops that are coming back from active service".
