The director revealed that the scene was originally inspired by a moment of tenderness in Witness starring Kelly McGillis and Harrison Ford, Si Fi Wire reports.
McG said: "It just felt like: 'Oh, there's the genre stunt of the good looking girl taking her top off.' It felt counterproductive in the spirit of what we were looking to achieve on a storytelling level.
"I suspect it will be on the DVD. I don't know, ask Moon. She was very passionate in sort of a third-wave feminist take on the whole thing. It was a fun conversation to have."
He added to WENN: "I didn't want people to have a reason to say, 'I can't take this film that seriously. They're still playing grab-ass and the film's made by a bunch of teenagers who just want the boob shot.'"
The director had previously said that he would not remove the half-naked scene in order to receive a lower age classification for the movie from the MPAA.
