Anyone who watched ER back in the day will recognise English actress Alex Kingston as Dr. Elizabeth Corday from the medical drama. In the '90s, she also starred in the British miniseries The Fortunes and Misfortunes of Moll Flanders.
More recently, she's best known for playing River Song in Doctor Who, as well as her appearances in Lost in Austen and Arrow. She starred alongside her The Widow castmate Louise Brealey in A Discovery of Witches, too.
