Wil Johnson is a British actor with some series experience under his acting belt though admittedly I've not seen any of it. I for one am interested in hearing Joe Abernathy's accent come out of this accomplished actor. If you want to know more about Wil you can check out his IMDB page or follow him on Twitter.
John Bell is a young actor who just happens to have been in two of the Hobbit movies with our beloved Graham MacTavish. I suppose if we can't have a certain dwarf we can have Bard's son Bain. Works for me though Graham is so missed. You can see more of the young actors credits at his IMDB page or follow him on Twitter.
Bell's Young Ian is set to join Jamie's (Sam Heughan) world in the 18th century, and Johnson's Joe Abernathy will meet Claire (Caitriona Balfe) in Boston in the 20th century, acting as her new friend and medical colleague.
Described as a tall, gangly Scottish lad with a heart of gold, a stubborn streak and a penchant for getting in trouble, Young Ian Murray is more like his adventurous and fierce uncle Jamie than his farmer father, Ian. While fans will meet him as a very gawky boy, we'll see him grow into quite a formidable man as the series evolves.
As for Joe Abernathy, he's a fellow doctor-in-training whom Claire befriends in medical school, and is described as intelligent and charismatic. Fans can expect to see Joe become a loyal confidant for Claire, as they both feel out of place in the mostly all-white, all-male medical field, a struggle that will bond them together in a life-long friendship.
