‘So Kieran came up with the role of Dr. Plowp and in a crazy turn of events, the bird alien (the character he plays) had four brothers (in the script) before he was cast,” Dunlap shared. The Hollywood Reporter.
“So he already had the four brothers and when we cast Kieran we were like, ‘You have four brothers!’ That’s ridiculous, what a fate,” Dunlap continued.
“Kieran was the one who suggested it, he said, ‘We can get my brothers’ and I said, ‘What? Yes, yes we should do that.’ And they’re so great, they’re so funny, they’re very empathetic and very sweet.”
However, it turns out that Natasha Lyonne, who plays Nurse Tup on the show, was the one who sealed the deal.
“Natasha’s magic, she called – I think she picked up the Culkin Batphone and they all answered,” joked Maya Rudolph, who is lining up to lend her voice to Dr. Flame.
Natasha said at the time: “I’m the Culkin whisperer, it turns out.”
“I worked with Mac on Party Monster, I want to say it was five years ago but it was probably 25. And so we became friends, we were friends straight away and he would do charades and the family would all be there. Kieran and I have become friends along the way, I think I might have made a film with Rory.
“I love them, I really love those Culkins,” she added.
