British actor Tom Cullen was tapped to fill the rather large shoes of Dan Stevens, stepping into the role of playing opposite Michelle Dockery’s Lady Mary on hit period drama Downton Abbey.

Downton Abbey's Tom Cullen

When Matthew Crawley met his end in a tragic car accident, it opened the door for a new man to get close to Lady Mary – after a period of mourning, of course. With roughly a year since Matthew’s passing and Lady Mary exchanging her blacks for a purple dress last episode, it might be time for Cullen’s Lord Gillingham to make his move.

While Cullen is an unfamiliar face for Downton Abbey’s stateside fans, he’s rather well known over in the U.K. His breakthrough role was in 2011, portraying a gay man in the critically acclaimed feature film Weekend. Prior to landing the role on Downton, Cullen’s TV credits included the World Without End miniseries.

Cullen's Upcoming Film Projects

Currently, Cullen has a few projects in the works, including Desert Dancer, in which he plays true-life Iranian dancer Afshin Ghaffarian alongside Freida Pinto. He’ll also appear in The Last Days on Mars, a sci-fi film, with Liev Schreiber and Romola Garai.

Cullen might be a bachelor on Downton Abbey looking for love with Lady Mary, but in real life, the 28-year-old actor is in a long-term relationship with Canadian actress Tatiana Maslany.
