The actress, 42, discussed her upcoming coming-of-age dramedy Belfast during an interview with Variety, including how her role influenced her decision to become a mom. In the film, Balfe plays the mother of a young boy amid the unrest in Northern Ireland in the 1960s. She said it was "not long after" she wrapped shooting the movie that she found out she was going to become a mother in real life, too. "I decided I was having so much fun playing a mother, I would just go for it," she joked, adding that she thoroughly enjoyed spending time with some of the child actors on set — including Jude Hill, Lewis McAskie, and Lara McDonnell. She continued, "They're just the most amazing kids, their mums were so cool, I was in a bubble with them and I think it sort of gives you a kick just to be like 'I'll do it. Why not?'
