Carter has continued to alternate between genres in the years since "Downton" began. He's taken roles in everything from a Transformers sequel to crime thrillers like "The Good Liar" and more. In 2019, he was honored for "services to drama" with the Order of the British Empire (OBE). His next film is a still-undisclosed role in "Wonka."
