When they weren’t learning curse words from Matt, his co-star Natasia demetriou, who plays Nadja, said they were a blast to have around—even if they might be messed up for the rest of their lives.

CelebHomes spoke to Natasia, who said that it was great having children on the set. “But every now and then, we’d say, ‘We’ve all got fangs in,’ so I think we might have damaged them in that they’ll never be scared of anything again because we were the friendliest monsters in the world. Every time they did a line, it was like, ‘High five! Woo!'”
