It's not easy being a period piece in the age of the Internet. Everybody's just waiting for you to slip up and make that one little anachronistic mistake — the wrong dress, the wrong meal, the wrong book. But, someone at Downton Abbey really messed up this week. The show released a promo photo that included a plastic water bottle in the background. Oops.
The snafu forced Downton devotees to confront the truth: The show is not real. It is not a recently discovered 1920s reality show. And, though the '20s had flappers, jazz, and gin, it had neither reality TV nor purified water. To acknowledge the mistake — or rub it in — the show's official Instagram posted a photo of the cast in their real-life clothes holding water bottles. And, it used the snap as an opportunity to link to Water Aid UK, a nonprofit that works to provide access to safe drinking water and sanitation around the world.
