Harrison Ford, star of Ender's Game, told reporters Thursday that he believes the anti-gay views of Orson Scott Card, author of the film's source material, are irrelevant to the themes and content of the upcoming science fiction opus. Moreover, he celebrated the ideas within that source material, suggesting that its exploration of humankind's "moral responsibility" is important and valuable.

"I think none of Mr. Card's concerns regarding the issue of gay marriage are part of the thematics of this film," Ford said Thursday during a press conference for Ender's Game at Comic-Con International in San Diego. "He has written something that is of value to us all to consider our moral responsibilities."

The fate of Ender's Game has become a tug-of-war between the film's distributor, Lionsgate, and a growing number of opponents to Card's past anti-gay and anti-gay marriage statements, who have called for a boycott of the film. In a seeming effort to divert criticism from the film, Card went noticeably absent from promotion of Ender's Game, and made a public statement calling the gay marriage issue "moot." Ford declined to offer his thoughts about Card's opinions.

"I think his views outside of those that we deal with in this film are not an issue for me to deal with, so I have really no opinion on that issue," the actor said. "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."

Ford championed the Supreme Court's recent ruling that same-sex couple were entitled to federal benefits, saying that it was a victory for all people. "I think we all know that we've all won, that humanity has won," he said. "And I think that's the end of the story."

Ender's Game opens in theaters November 1, 2013.
