Anti-gay author Orson Scott Card will not make money from ticket sales of the Ender’s Game film, which is based on his novel, potentially rendering a boycott of the film meaningless.

An online campaign urged moviegoers to boycott the upcoming release of “Ender’s Game,” a big-budget Hollywood movie based on the work of notoriously anti-gay novelist Orson Scott Card, who last year described same-sex attraction as a “reproductive dysfunction”.

The pay packet of the author, however, was finalised ten years ago, according to The Wrap, and there were no bonuses tied to box office sales, so he would be unaffected by a boycott.

Actor Harrison Ford, who stars in the film last month again defended the Ender’s Game film, which received heavy criticism because of the anti-gay views of Card.

At Comic-Con there were no signs of any protest, despite the calls for a boycott. The film’s director also commented to say that the book the film is based on is “great”, and “is not about” equal marriage.

Screenwriter of the Harvey Milk Biopic ‘Milk’, Dustin Lance Black, weighed into the argument to say that the campaign to boycott the film is “misguided”.

Producing the film, Lionsgate responded, saying it has a longstanding commitment to the LGBT community, and that although it does not agree with Card’s personal opinions they are not linked to the book or the film.

The proponents of the boycott then replied to reject Card’s call for tolerance.

In a more recent interview, Card called criticisms of his anti-gay views “savage, lying deceptive personal attacks.”
