The creator of the period drama - which came to an end at the latter part of last year following five years on screen - believes his masterpiece would have been made into a blockbuster by now if it wasn't for the likes of Hugh Bonneville and Michelle Dockery slowing things down.

Speaking on 'Loose Women' today (14.04.16), he said: "Let's just say it's not me slowing things down. The difficulty is rounding up the actors. One is in America making a new series, another is in a play ... My lips are sealed!"

But the 66-year-old talent is almost certain that the popular series will eventually hit the big screen because fans are so desperate to see the cast reunite for one more memorable stint at the famous Yorkshire country estate.

He explained: "It's very unlikely there won't be a film because there is an audience out there for it. I do hope there is going to be a 'Downton Abbey' film. It's going to be fun once everything is sorted but we just need to restructure it."
