NBC’s upcoming drama Dracula added Katie McGrath and Nonso Anozie on Wednesday.

TV Line reports McGrath (Merlin) and Anozie (Game of Thrones) are joining the show as regulars. Jonathan Rhys Meyers (The Tudors) and Jessica De Gouw (Arrow) are the other known cast members at this time.

Dracula is based on Bram Stoker’s book Dracula, but offers a different look at the story. As we previously reported, the show will take place in 1890s London. Dracula is an American businessman in the series who goes to London under the pretense of helping introduce modern science. His real motive is to extract vengeance on people that hurt him years before. However, he encounters a woman who looks like, and may be a reincarnation of his deceased wife.

McGrath will play Lucy Westenra, an aristocratic lady who is friends with Mina Murray (Jessica De Gouw). Lucy’s descent into trouble will be problematic when it comes to her friendship with Mina.

Anozie will play R.M. Renfield, a close companion of Dracula’s (Jonathan Rhys Meyers) other persona Alan Grayson. He knows Dracula’s secrets and helps him manage his roles as Grayson and Dracula.

The Hollywood Reporter believes the show will premiere sometime in the fall.

NBC has ordered 10 episodes of the drama.
