On the 25th anniversary of the September 11 attacks, celebrities including Nicole Kidman, Alix Earle and Viola Davis volunteered with the Cantor Fitzgerald Relief Fund. Broader commemorative coverage included reflections on lingering questions about EPA claims that the air near Ground Zero was safe following the attacks, a report on a possible fifth hijacked plane that was never publicly confirmed, retrospectives on how television and literature have depicted 9/11 over 25 years, and the story of two Juilliard students whose Sing for Hope piano project grew out of the tragedy. Together, the coverage reflects the range of ways the entertainment and cultural world marked the milestone anniversary, from star-studded volunteer efforts to investigative and artistic retrospectives.
