The popular period piece is currently searching for an actor to encompass the role of musician Jack Ross as part of a storyline tied to 1920s race relations.

According to The Sun, casting notes from the show were sent to actors' agents earlier in February that described the Jack character as "25-30.  A musician (singer) at an exclusive club in the 20s.  He's black and very handsome.  A real man (not a boy) with charm and charisma."

The character bio also goes on to state that whoever lands the role should "ideally be able to sing brilliantly. Overall he should be a very attractive man with a certain wow factor." 

The newbie part won't be the only addition to Downton Abbey when it once again hits television screens. Lady Mary Crawley will also reportedly be given a new flame on the show in Lord Anthony Gillingham, who will be assisting the family with their money problems.

The casting notes describe Gillingham as a "good looking, very charismatic" 35 to 45-year-old with a "perfect cut glass accent. He's warm and charming, but also a strong man with morals." It had been rumored that the coveted role has already been filled by EastEnders and Miranda standout Tom Ellis.

Lady Mary was left heart broken at the end of the third season when her beau Matthew Crawley abruptly died in a car crash.

Sir John Bullock, a party-loving man, is also another new role in fruition for the upcoming season.

Downton Abbey Season four is slated to start production on March 23.
