If there is one person who is most likely to have the hardest time saying goodbye to "Downton Abbey," it must be its series creator Julian Fellowes.

The award-winning scriptwriter/ director recently talked to the press about the upcoming end of his internationally acclaimed period drama. In an interview with Variety, Fellowes admitted that it feels strange writing the conclusion of "Downton Abbey" since he had been working on it with a group of incredible people for the past seven years. He also admitted to feeling sad whenever he had to come up with the last line for a specific character. However, Fellowes believes that ending the series after its sixth season is the right thing to do since he does not want the show to overstay its welcome. 

The 65-year-old British scribe wrote all eight episodes of "Downton Abbey" season 6, as well as the Christmas special episode that will also air later this year. 

The series creator admitted to The Wrap that it will be hard to replicate the success of "Downton Abbey" in his future projects since the series has become an international phenomenon and is hailed as the most-nominated foreign show in the history of Emmy Awards during its past five seasons. 

The production of "Downton Abbey" season 6 is still in progress. Several set photos reveal that Tom Branson (Allen Leech) already returned from Boston, and Ms. Hughes (Phyllis Logan) and Mr. Carson (Jim Carter) will finally get married. 

But the series creator confessed that he and the rest of the cast and crew of the show are already getting emotional as they prepare for the final sequences of filming. He also predicted that they will have a wrap party after the last scene is shot, where everyone will undoubtedly sob as they bid farewell to the series. 

For Fellowes, working on a phenomenal hit like "Downton Abbey" had been an "extraordinary adventure," and he is very grateful for the said experience. 

"If this is my last hit, it's not a bad thing to have," the series creator said. 

"Downton Abbey" season 6 premieres in November on ITV in the U.K., and its U.S. audience will get to see the final episodes of the series on PBS after its U.K. airing.
