UNICEF is privileged to have a long history of support from ambassadors and high profile celebrity supporters, starting with movie star Danny Kaye in 1954 and including influential names like Audrey Hepburn and Sir Peter Ustinov.
Right now we're proud to work with a number of hard-working ambassadors and supporters, who demonstrate an amazing commitment to UNICEF's mission for children worldwide. This photo gallery shows just a small sample of the great work they've done.
Actor Ewan McGregor has been a UNICEF ambassador since 2004 and has filmed several documentaries with us including the recent BBC show Cold Chain Mission, about UNICEF's work on vaccinations for children.
This photo was taken in 2010, when Ewan visited Peru for Soccer Aid to find out about our work on child poverty and malnutrition.
