After the success of the television series, Downton Abbey had an encore with its movie, which was initially released a couple of days ago. But due to the success of its cast, the series creator Julian Fellowes said that the production of the movie was a logistical nightmare.
Speaking on CBS Sunday Morning, Fellowes said: "To the wider public, none of the young ones were really known, and now they're all famous around the world.
"They were doing shows on Broadway and movies and series in Hollywood and plays in London and God knows what.
"They all had to be extracted for a kind of 12-week period, and I think that was a logistical nightmare, but we happily got there in the end."
