Director Gavin Hood Speaks On The Irony Of ‘Ender’s Game’

He gets right to the point:

“It’s dreadfully ironic. Orson wrote a book about compassion, and empathy, and yet he himself is struggling to see that his position in real life is really at odds with his art.”

Though not without some apologia:

"I think what would be far more helpful is if audiences knew that the makers of this film, and the film itself, holds the polar opposite point of view to the current thinking of Orson Scott Card on gay issues.” 

Also present are the misconceptions that people are protesting the film itself rather than the author, and that people have trouble viewing art independent from the artist. The Advocate has the full piece, which also includes statements from Harrison Ford and producer Roberto Orci.
