That's addressed in the Wiki article I linked to, Don. I'm a bit wary of what the film will be myself.

On the subject of gay marriage, Card said, " Ender's Game is set more than a century in the future and has nothing to do with political issues that did not exist when the book was written in 1984. With the recent Supreme Court ruling, the gay marriage issue becomes moot. The Full Faith and Credit clause of the Constitution will, sooner or later, give legal force in every state to any marriage contract recognized by any other state. Now it will be interesting to see whether the victorious proponents of gay marriage will show tolerance toward those who disagreed with them when the issue was still in dispute."

Harrison Ford has stated, ""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."''
