Leonardo DiCaprio is making good on his promise to help the Academy of Motion Picture Arts & Sciences open the world's first museum dedicated to film. 


On Wednesday, officials announced that the 37-year-old was the lead benefactor from a group of donors in securing an original pair of ruby red slippers from the timeless classic "The Wizard of Oz." This “holy grail of all Hollywood memorabilia,” one of four pairs made for the film, will reside in the future Academy Museum in Los Angeles. 


“Leo’s passionate leadership has helped us bring home this legendary piece of movie history,” said Academy CEO Dawn Hudson. “It’s a wonderful gift to the Academy museum project, and a perfect representation of the work we do year-round to preserve and share our film heritage.”


The "J. Edgar" actor spearheaded a group that included Steven Spielberg and co-chair of the Los Angeles County Museum of Art, Terry Semel, among others. The cost of the acquisition was not revealed. However, in December 2011, the same slippers were auctioned online with a starting bid of $2 million, but were never sold


“Of the four pairs of authentic ruby slippers known to exist, this pair offered by Profiles in History, marked ‘#7 Judy Garland’ and known as the ‘Witch’s Shoes,’ are the most important and most valuable,” Oz expert and author Rhys Thomas said in the release.


Last November, DiCaprio co-chaired an inaugural fundraiser for the LACMA movie museum, raising some $3 million from attendees such as Clint Eastwood, Kate Hudson, Ron Howard, Olivia Wilde, Jane Fonda and Harvey Weinstein.


“As a native of Los Angeles, I want to personally thank everyone associated with LACMA,” The Hollywood Reporter quoted DiCaprio in his remarks. “Your commitment to serve the public through conservation, exhibitions and your interpretation of significant works of art continues to have a valuable impact on our community here in Los Angeles.”
