The adventure of Jamie (Sam Heughan) and Claire (Caitriona Balfe) will continue in “Outlander” season 4 in the American Colonies. Filming of the show has been ongoing for a while now, and two important characters have already been cast.

Thousands of miles from home, Jamie will manage to meet a relative in America. The role of Aunt Jocasta will be played by Marla Doyle Kennedy, famous for her role in “Orphan Black.”

Jocasta’s husband is Hector Cameron, who owns a plantation in America called River Run. The couple had migrated after the Battle of Culloden. A plantation obviously means there will be slaves there, and one important character here is the butler Ulysses.

According to a report by Entertainment Weekly, Ulysses will be played by UK actor Colin McFarlane. The actor is known for his work in movies like “Batman Begins” and “The Dark Knight.” According to the character description, Ulysses is a well-educated and musically inclined man who was sold into slavery at a very young age. He becomes a trusted servant of Jocasta and will help manage the other slaves at the plantation.

Ulysses is an important character in the books written by Diana Gabaldon; he may be coming back for the next few seasons if the producers follow the story. The next season is based on the novel “Drums of Autumn.”

Casting news has already spread like wildfire, with McFarlane getting a lot of followers on his Twitter. The actor thanked the fans for following him on the social media platform (see below). He hopes his new followers will “work their magic” and get Twitter to finally verify his account. The actor has been working in the industry since 1985.
