A couple major characters may be out of Downton Abbey Season 4 - Dan Stevens as Matthew, Siobhan Finneran as O'Brien - but Executive Producer Gareth Neame has come out and shared some exciting casting news:

Shirley MacLaine will return for next season's finale, while SIX new characters will be introduced.

"Downton Abbey has seen many great characters visit the house over the years and we couldn't be more thrilled to welcome the new faces that will be joining the regular cast of Downton Abbey in Season 4," Neamet tells PBS. "We hope audiences will be as excited about them as we are."
