Five actors have joined “Outlander” season 4, and one of them is a “Lord of the Rings” alumni. The announcement was made online, and the new cast members got a warm welcome online from their fellow cast members and from the excited fan base.

The new cast members on the show are Billy Boyd, Caitlin O’Ryan, Natalie Simpson, Tim Downie, and Simona Brown. Downie took to Twitter to share his excitement about being a part of the show, and working with Sam Heughan (Jamie) and Caitriona Balfe (Claire) [see below].

As far as the characters that the new cast members will play on the show, Entertainment Weekly shared some details about the character descriptions.
