Today, Mark Hamill announced details for this week’s campaign sponsored by CrowdRise in support of Star Wars: Force for Change. Since April 5th, Star Wars: Force for Change, an initiative that inspires people to make a positive impact on the world, has been matching the donations of Star Wars fans to four select charities up to $1,000,000!

This week, the top fundraiser will get a trip to London including tickets to attend Star Wars Celebration Europe where they will meet Mark Hamill.

This month-long campaign will lead up to “Star Wars Day” on May the 4th. The four select charities include the U.S. Fund for UNICEF in support of UNICEF Kid Power, American Red Cross, Boys & Girls Clubs of America, and Make-A-Wish®.

Over the course of the four-week period, which culminates at 11:59pm (PST) on May 4th, fans will be able to donate through CrowdRise.com/ForceForChange to these four charities and have their donations matched dollar for dollar up to $1,000,000. All participants who enter will also have a chance to win an all-expense paid trip to Ireland, including Skellig Michael along the Wild Atlantic Way, the location of the dramatic final scene from The Force Awakens.
