Accent
So glad he doesn't have to do an American accent in Lucifer
shareYour own conclusion contradicts your question, since David Tennant is Welsh and was putting on a more English accent for Doctor Who. Like someone else mentioned, Lucifer's accent is mostly a London RP with a bit of Mockney. It's a mash up. Tom's own accent is very much Welsh.
