The iconic Hollywood sign that hangs in Cahuenga Peak has inspired countless stars who have made their own iconic contributions to the glittering city. Hugh Hefner, founder of Playboy, compares the sign to the Eiffel Tower. He told the Los Angeles Times the image of Hollywood had a "major influence" on his own career.

To preserve the sign that played such an important role in his own career, Hugh Hefner and other celebs including Steven Spielberg, Tom Hanks and Arnold Schwarzenegger have given funds to boost the nonprofit fundraising efforts of the Trust for Public Land.

The trust will use the millions of dollars contributed by supporters of Cahuenga Peak to make the peak part of the protected Griffith Park. Will Rogers, president of the TPL, says the funds - which the nonprofit struggled to find before A-listers stepped in to help - have created a perfect "Hollywood ending" for the preservation effort.

John Donnelly, executive director of the Wildlife Conservation Board, told the trust, "the permanent protection of Cahuenga Peak is a significant addition to Griffith park that will greatly enhance recreation opportunities for visitors and residents."

Other preservation organizations might consider asking celebrities to support their causes. Additionally, this story shows that emphasizing the cultural significance of endangered landmarks can help gain funds, even in the final hour.
