Steven Spielberg, Tom Hanks and Oprah Winfrey are among the media figures featured in a series of public service announcements unveiled on Wednesday as part of First Lady Michelle Obama and Jill Biden’s initiative to support military families.

The First Lady was in Los Angeles in June to address a task force of Hollywood’s guilds and pitch the idea of integrating stories of military families in movie and TV storylines.

Producer Bruce Cohen, who leads the task force, assembled the production team to create the three PSAs, with music from Hans Zimmer. Among those also involved in the production were “Army Wives” creator Katherine Fugate, “Lost” executive producer Damon Lindelof and director Tom Shadyac.

A&E Networks, CBS, Comcast, NBC, Disney ABC, Fox and Warner Bros. have agreed to support the PSA campaign.

“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,” Michelle Obama said in a statement.

The Spielberg PSA is here; Hanks is here; and Winfrey is here.
