The company also released an unedited transcript of the clip.
Balfe said: “It’s a particular place in Shotts. I just want to be specific. It’s not the town – the little village.
“They found an old dump that was also kind of a swamp, and we were there for over a week, and our sets kept getting attacked, and it was not my favourite place.”
The Daily Record, external reported that Dublin-born Balfe and the Outlander crew filmed near Hartwood Hill, near the site of an abandoned hospital in 2024.
However a source claimed the shoot was disrupted by gangs of youths, who stole a quad bike and set it on fire.
The production also had problems with the ground being impenetrable.
The Spotlight Shotts community group previously told BBC Scotland News the flippant comment was hurtful to people in the town.
Outlander, which concluded earlier this year, focused on the relationship between Balfe’s character – a nurse in the present day – and Heughan, who played Jacobite Jamie Fraser.
The show has been praised for boosting Scotland’s tourism.
