The movie received an NC-17 rating in October thanks largely to a full-frontal nude scene featuring Fassbender. In a recent interview, the actor admitted that he is frustrated by this rating, which will limit the amount of cinemas in which the film can be shown.
"Half of us have a penis and the other half have probably seen one, and so why should it be more normal to, like, chop people's heads off and shoot people?" he asked the Huffington Post. "Does that mean that that's more acceptable or closer to us as human beings?"
He went on to say that he is annoyed by the tendency to repress any discussion of sex.
"Most of us have sex, so I don't understand what we're trying to sweep under the carpet or repress or not take a look at it," Fassbender said.
The actor's co-star Carey Mulligan previously slammed US censors for awarding the movie an NC-17 rating, insisting that the rating is due to the fact that the film depicts "unattractive" sex scenes.
