Filming of “Outlander” season 4 is currently underway in Scotland. Co-executive producer Maril Davis gave fans an update about how things are progressing in an online Q&A. Cast members César Domboy and Romann Berrux also answered fan questions in a separate Q&A session.

There will also be 13 episodes in the fourth season, Davis confirmed. The cast and crew are currently filming the first block. Production is broken up into blocks, and each block consists of two episodes each. It takes 12 days to film an episode, and the entire filming wraps up in about 10 months, after which post-production starts.

Although filming has started, not all scripts are ready at the moment. Davis said they are half way through when it comes to these.

There are two filming units used this year. The main unit films on location and does the bulk of the work. The secondary unit films “pieces” or scenes that the main unit couldn’t finish during the scheduled days.

Fans will get to see more of Roger (Richard Rankin) and Brianna (Sophie Skelton) in season 4. However, the story essentially still remains focused on Jamie (Sam Heughan) and Claire (Caitriona Balfe).

The story takes the main characters to the US, but filming will mostly take place in Scotland. It isn’t clear which other countries the cast and crew will travel to. Davis confirmed they will certainly not be filming in the US, and admitted that they will not be able to capture the North Carolina weather because of this.

Meanwhile Domboy and Berrux, who both play the role of the character Fergus, answered a few questions online. Domboy revealed =he will be getting a wooden hand instead of a hook on the show, and Berrux said the scene in which his hand gets chopped off was one of the most difficult scenes to do.
