"Star Wars: The Last Jedi" film director, Rian Johnson, has finally revealed who the last Jedi is in the eighth episode installment of the "Star Wars" franchise.

Johnson, on his talk with Good Morning America, has clarified that the title "Star Wars: The Last Jedi" is singular - despite all the debate suggesting otherwise. He also confirmed that the titular "last Jedi" is none other than Luke Skywalker (Mark Hamill).

"It's so funny when people started asking that when the title was announced because I never even pondered that question... In my mind its singular," he said when the "last Jedi" controversy was brought up. "They say in The Force Awakens that he's gone on to find the last Jedi temple. Luke is the last Jedi."

Many fans of "Star Wars" have debated whether "The Last Jedi" is singular or plural when it was officially announced. Some were convinced that the title was plural due to the posters spotted in other languages, as previously reported by Slash Films.

According to Cinemablend, Johnson's revelation about Luke being the last Jedi makes total sense. He was the last one to have direct connection with the Jedi order and was briefly trained by Obi-Wan and Yoda before they both perished. Because of the two Jedi Masters' death, the true teachings and lineage of the Jedi Order has perished as well, thus making Luke the last in "Star Wars: The Last Jedi" makes sense, as explained on the report.

Meanwhile, Disney and Lucasfilm has officially released the first teaser trailer for "Star Wars: The Last Jedi" and it was showcased during the annual event Star Wars Celebration day last week at Orlando, Florida. And to many fans' surprise, Gwendoline Christie's Captain Phasma has returned after being dumped down a garbage chute in "Star Wars: The Force Awakens," The Guardian reported.

"Star Wars: The Last Jedi" is scheduled to premiere in cinemas on Dec. 15, 2017.
