A few days ago, Downton Abbey caused a bit of a stir when a very clear anachronism appeared in a promo photo: a water bottle on the mantel above Lady Edith. But the cast bounced back with aplomb, posting an Instagram photo of themselves holding — wait for it — bottles of water! They also turned attention to the international work of WaterAid, a nonprofit that provides clean water to people around the world. Classy.
