On the Dark side of the force?

George Lucas has created legendary film heroes like Luke Skywalker and Indiana Jones, but the US director says that in real life, his hero is Barack Obama.

Lucas was in Japan on Wednesday to promote his latest film, "Indiana Jones and the Kingdom of the Crystal Skull," as Obama clinched the Democratic Party's nomination for president.

"We have a hero in the making back in the United States today because we have a new candidate for president of the United States, Barack Obama," Lucas said when asked who his childhood heroes were.

Obama, "for all of us that have dreams and hope, is a hero," Lucas said.

Lucas is the creator of the blockbuster "Star Wars" series, as well as the adventures of the swashbuckling archaeologist Indiana Jones, played by Harrison Ford.

Obama on Tuesday sealed the Democratic contest after a marathon battle with Hillary Clinton, becoming the first black White House candidate nominated by a major party.
