"Star Wars" fans swooned over episode 7 of the series, "The Force Awakens," but there is one key moment in the movie that director J.J. Abrams could not have shot without help from his friend and "Selma" director Ava DuVernay.

It was DuVernay’s suggestion that inspired the final confrontation scene between Rey (Daisy Ridley) and Kylo Ren (Adam Driver) where Rey has a quiet moment in which she thinks of The Force as she is holding off Kylo’s lightsaber. After the moment of reflection, Rey delivers a decisive blow to her opponent, making the scene important to the movie’s story.

“I showed an early cut to my friend Ava DuVernay , and she had a bunch of great suggestions. One of them was she really wanted to see Daisy, in her attack on Ren, have one really cool moment,” Abrams said in a commentary track from the four-disc "Force Awakens" 3D collector’s edition, releasing in the U.S. on Nov. 15, according to Yahoo.

The collector’s edition offers the theatrical version of the film on Blu-ray 3D, Blu-ray, Digital HD and DVD in addition to Abrams’ commentary track.

The scene was shot during an eight-week break in principal photography due to Harrison Ford’s injury.

Back in December 2015, Abrams said in an interview to the Nerdist that DuVernay would "kill it," if she were to direct "Star Wars."

DuVernay is currently working on the sci-fi adaptation of Madeleine L'Engle’s 1963 novel “A Wrinkle In Time.”
