The show, which takes place in the early 20th century, has recently finished its third season, but Julian is sure that if it does come back for a fourth season he will include a role for an actor from an ethnic minority.
"The show certainly ought to have an Indian character from that period. You have to work it in a way that is historically believable but I am sure we could do that," Julian said.
Christmas special in the works
Although the only future planned episode is a Christmas special, Julian is pleased with how the first three seasons have been received and how the characters, played by a cast including Dame Maggie Smith, Michelle Dockery and Hugh Bonneville, have developed.
"I felt the second series was more solid than the first because we knew who they all were. And now we are really involved with them and that takes you forward another step.
"I am pleased with all of them really. It sounds rather smug but I have been very happy," Julian believes.
