While the season finale of "Downton Abbey" is imminent, it looks like the writers and creators of the series are leaving a movie option open.

Recently in an interview with Deadline, Downton Abbey creator Julian Fellowes revealed that the show will not be wrapping up every plot line and arc. Fellowes notes that since the series has been popular, there could potentially be spin-offs or possibly even a movie.

He said, "I think to have [the characters] all killed in a bus [in the finale] would be a mistake," Fellowes said. "I think we bring various things to a conclusion and anything unresolved is unresolved. I'm open to the idea of a movie but I'm not anxious to do it."

Fellowes said he's hesitant about a movie because he believes TV shows that are turned into movies do not turn out very good. 

He said, "In my experience, and naming no names, the movie of the series is often a disappointment. Normally they're not very good because the film producer says, 'Oh, it's not going to be anything like the series,' and of course what you want is for it to be exactly like the series. I hope we would avoid that error in doing one, but I do have mixed feelings about it."

Producer Gareth Neame was not completely opposed to the idea and said, "We are up for doing it, the cast is up for doing it. There are a lot of things to work out. We have the ambition to do it, but no firm plan about it or when it would happen."

Recently, "Entourage" was disliked by critics and the film flopped. On the other hand, "Sex and the City" was a box office hit but like "Entourage" did terribly with critics. "The A Team" and "The Smurfs" also opened to mixed reception.

"Downton Abbey" is also an interesting show since it was shown on PBS and it is also a period series. Period films are not summer fare and they are definitely not box office hitters. 

While the show could easily be a popular hit on TV, it would be interesting how many regular viewer would make it out to a multiplex to see their favorite characters.
