Paul Giamatti will be joining the cast of Downton Abbey for the fourth series of the hugely popular TV series.

The actor best known for his roles in 'Cinderella Man' and 'Sideways' will play the part of Harold Levinson, the 'maverick playboy' brother to Cora and Uncle to Mary and Edith. However, Harold won't appear in the show until the season finale along with their mother, played by Shirley MacLaine. 

We still have not recovered from Dan Stevens sudden exit from the show but Downton Abbey have lined up some eye candy to keep us interested, in the shape of Tom Cullen, Nigel Harman, Julian Ovenden and Gary Carr. They will also be joined by fellow newbies Dame Kiri Te Kanawa, Joanna David and Dame Harriet Walter. Hugh Bonneville, Dame Maggie Smith, Michelle Dockery, Shirley MacLaine and Jim Carter will all be returning for the fourth season.

The fourth series returns to our screens in the autumn.
