As world leaders convened Monday at United Nations headquarters in New York to kick off this year’s general assembly, they were presented with a world premiere of a new short film featuring Prince Harry, Charlize Theron, Earvin “Magic” Johnson and Thuso Mbedu. The high-profile stars appear in the short along with two HIV+ activists, all of whom offered up their time and words to rally support for HIV/AIDS amid global cutbacks with a clear and hopeful message —to end AIDS as a public health threat by 2030. The two-minute, 34-second clip hails from UNAIDS, the joint United Nations program on HIV/AIDS, which unites 11 UN organizations, including UNHCR, UNICEF, WFP, UNDP, UNFPA, UNODC, UN Women, ILO, UNESCO, WHO and the World Bank.
