The benefit of a series like “Downton Abbey” is that there’s so much history to choose from and interact with in the early 20th century. When it came time to brainstorm ideas for “The Motion Picture,” Julian Fellowes looked to the past. . The first feature shows Downton folks scrambling to make room for the royal visit of King George V (Simon Jones) and Queen Mary (Geraldine James).
Based on Town & Country, the idea came to Fellowes after reading about the royal couple’s history. In 1912, they visited Wentworth Woodhouse, which is primarily known as the UK’s largest private residence. Fellowes said: “I wanted something that would affect both the family and the servants. I don’t care about the royal family, but I understand why he would see how their wonderful presence affects those at Downton, especially Mr Molesley, Mr Molesley, Kevin Doyle’s super nervous.
It’s worth mentioning that King George V and Queen Mary then actually visited Highclere Castle more than five years later in 1917. It’s easy to see why Fellowes would choose another visit, considering their arrival at the castle. The mansion is around the time it was converted into a makeshift hospital during World War I. If anything, I’m surprised the series never got the chance to make that into a second season.
