Sam Heughan of 'Outlander' Thanks Show's Cast after Finale and Says He Is Proud of Season 5

Sam Heughan wants to let the world know just how he feels about the success of "Outlander." The show's season finale was as humbling as it was explosive.

After the mind-blowing finale of Starz's "Outlander," Sam Heughan took to Instagram to share his appreciation for his colleagues and to shower praise on all of season five.

He also called out co-star Caitriona Balfe, who played a huge role in the last episode. Of course, fans rushed to agree with him in the comments. The post is found below.

"What a finale! Proud of this season. So many terrific episodes," wrote the actor. He went on to thank the cast and crew before calling Balfe "brilliant" for her work in the finale.

Heughan accompanied the caption with a photo of him and Balfe. The post garnered nearly 290k likes in its first 48 hours only. "Wow! What an episode," one fan echoed in the comments.

Earlier this week, Heughan did a commentary on the shocking last episode of "Outlander" for Elle magazine. The first-time producer of the show said they were unsure about the finale at first.

He explained: "It's very disturbing and graphic and challenging, so we wanted to get it right." Alongside co-producer Balfe and director Jamie Payne, they focused on getting the tone just how they wanted it.

The character Claire goes through some trauma, but they didn't want it to be too dark. He added: "We wanted to be sure we were honest and truthful to the narrative, but also to the situation she's in."

In a separate interview done on the podcast "Can't Stop Watching," Heughan said that the dramatic scene with Claire (Balfe) left him pondering his episode highlights.

Again, the actor pointed to tone and the importance of making it less about "brutality" and more about how Claire dealt with what she went through. She ends up back with her love, Jamie, in the end.

The abusive actions of the show prompted fans to react strongly on Twitter. Much of it was praise for Marsali, played by actress Lauren Lyle, who killed an antagonist on the show.

"Marsali really shines this season. I soo love her," wrote one viewer. Elsewhere, some fans were left wondering if Brianna and Roger would use their abilities to ever return to the 1970s.

While "Outlander" season six is guaranteed, eager fans will have to wait and see just how soon that can happen due to the pandemic going on. For now, the droughtlander begins.
