Lucy Lawless says it was 'difficult' joining 'Battlestar Galactica' because of the 'culture of anxiety' on the show

• Lucy Lawless told Business Insider there was a "culture of anxiety" on the "Battlestar Galactica" set.
• The actor joined the science fiction show in 2005 during season two.

Lucy Lawless told Business Insider that she found it difficult joining "Battlestar Galactica" because of a "culture of anxiety" among the show's actors who didn't know if they would get killed off.

Lawless joined the show's second season in 2005 as news reporter D'Anna Biers, who was later revealed to be a robotic Cylon named Number Three.

The character faced plenty of twists — including dying and being resurrected several times — and Lawless stayed on "Battlestar Galactica" until it ended in 2009.

Similarly to more modern shows like "Game of Thrones" and "House of the Dragon," "Battlestar Galactica" had shocking cliffhangers, brutal murders, and unexpected deaths throughout its seasons, helping it to garner a cult following.

The ruthless, unpredictable nature of the story made the set a difficult environment for anyone new joining the cast, Lawless said in an interview for BI's Role Play series

"It was difficult coming in, because they felt if I was coming in, then one of them was on the way out," she said. "They were really nice people so I could tell it wasn't because they were awful, but there was a little bit of a culture of fear. And that was a shame."

Lawless described the tense atmosphere among the actors on set, noting that there was intense pressure not to reveal spoilers.

"In my opinion, the actors were kept in a state of insecurity, which I don't agree with as an executive producer. I don't agree with that at all.

"Because they didn't want any spoilers getting out there at the time — people didn't know if they were going to be killed off, and they were extremely nervous. So there was a culture of anxiety on that show," she said.

The show mainly takes place on the titular military spaceship as the last remnants of humanity try to survive attacks from the race of sentient robots, the Cylons. According to Lawless, the setting didn't help with morale among the actors.

"You're filming all day in the dark. You get to work in the dark, you are in space all day, and then you come out, and it's dark again," she said. "That isn't conducive to a very joyful, lighthearted environment, because human beings need the green of trees and the blue of the sky and all that stuff to be truly mentally happy and nourished on some level."

Representatives for "Battlestar Galactica" producer Ronald D. Moore did not immediately respond to BI's request for comment.
