PBS Network's 'Downton Abbey' has just been officially renewed for a sixth season. However, there are rumors whether or not the show will go beyond six seasons or not. Will this spell the end for the Crawleys? Is it true that the doors of Downton Abbey are closing for good?

The British drama is currently airing its fifth season in the US, but there have been speculations that the hit TV series won't go beyond the sixth season. Series creator Julian Fellowes has told The Wallstreet Journal that the show, "won't go on forever. It won't be Perry Mason." This was during the time when the fourth season was being aired, and the show had just been renewed for a fifth season.

According to Express, details from a recent interview with Hugh Bonneville  who plays Lord Grantham on the show mentioned that Fellowes may not want to keep the series going on for too long because it's "taking up a lot of his time."

"This is all written by one person and there's only so much he can do," he said. "There will be a natural end."

While there have been talks as to when the British drama series might end, saying that the show might go on for at least a few more years, at most. However, Fellowes might want to quit while he is ahead when it comes to the ratings game.

In an earlier interview with Huffington Post Canada, Fellowes said that  "Unlike America, in England we have to wait until the season finishes [airing] before we receive a pick-up; we're not renewed multiple years in advance. We never want to jinx anything. That's good because it keeps everyone at the top of their game. If there is a sixth season, it may be our last."

Fans of the popular British show are concerned with the fate of their favorite characters as the show will ultimately draw to a close. While Fellowes has been confirmed as the writer for season six, there has been no news yet as to returning cast members.
