Coffee seems to be the one thing that all the cast members of “Outlander” season 4 can’t live without on the set. A new behind-the-scenes video has been released online that shows the actors tells viewers the five things they really need while filming.

In the video [see below] Sam Heughan (Jamie Fraser) says that he can’t live without his co-star Caitriona Balfe (Claire) on the set. Richard Rankin (Roger Wakefield) and Sophie Skelton (Brianna) were equally sweet when they said that they can’t live without the crew members, who support the cast and the directors by making sure they are all comfortable on the set.

César Domboy (Fergus) and Lauen Lyle (Marsali) would like a good Wi-Fi connection, which may have been a problem in some of the remote and woody locations where they have filmed this time around.

While all the cats members need their coffee, Ed Speleers (Stephen Bonnet) also likes some green tea. Speleers apparently needs his music on the set, which he describes as “paramount” to a day’s work.

Heughan and Balfe both need food on the set. “I couldn’t live without some sort of snack,” Heughan said. The actor also likes a warm coat, which should come in handy in all those night shoots the cast members have to endure every year.

Another video that has been released online shows Rankin and Skelton reading some fan tweets [see below]. The fans sent some interesting compliments for the two actors, which they read out aloud and had some fun with, sharing some behind-the-scenes insights about what went on while filming some big scenes together.

“Outlander” season 4 is set to premiere on Nov. 4. The plot will focus on the life of the Frasers in the American colonies and the life of Roger and Bree in the 1970s.
