Harrison Ford has spoken out about the controversial views of the author behind the story of his new movie Ender's Game, insisting his opinions are completely separate to the film. The sci-fi thriller is based on Orson Scott Card's 1895 graphic novel of the same name, but its transformation into a big screen movie has angered gays rights activists due to the author's frequently vocalised anti-gay marriage stance. Card openly showed his opposition to same-sex marriage in 2009 when he joined he board of the National Organization for Marriage, which opposes same-sex unions, but has since released a statement insisting that the book has nothing to do with his political views. And now Ford has distanced himself and the movie from Card, telling fans at Comic-Con in San Diego, California on Thursday (18Jul13), "I think none of Mr. Card's concerns regarding the issues of gay marriage are part of the thematic of this film. "He has written something that I think is of value to us all concerning moral responsibility. I think his views outside of those that we deal with in this film are not an issue for me to deal with and something I have really no opinion on. "I am aware of his statements admitting that the question of gay marriage is a battle that he lost and he admits that he lost it. I think we all know that we've all won. That humanity has won. And I think that's the end of the story."
