Baby Done premiere: Benee, Chris Mac, Suzy Cato et al answer awkward kid questions

New Zealand must be one of the only places in the world to be able to hold a 500-person-strong movie premiere at the moment, so it's no wonder the stars turned out this week to celebrate the release of the Kiwi flick, Baby Done

Written by Sophie Henderson and directed by her husband Curtis Vowell, the movie is loosely based on the filmmaking couple's experience of falling pregnant... and subsequently freaking out. 

"It was my way of coping," Henderson told Newshub. "I was like, 'I'm just going to write a movie instead of think about the baby!'" 

Rose Matafeo's character Zoe, experiencing many of the same emotions, doesn't write a movie, but she does attempt to do just about everything else under the sun before becoming a parent. Her partner Tim, played by Harry Potter star Matthew Lewis, has a more sensible approach to impending parenthood. But he still has no idea what he's doing, either. 

Matafeo and Lewis weren't able to be at the film's world premiere - they're already back overseas and working on their next big projects - but Newshub did have access to a cinema foyer filled with some of the country's most beloved celebrities. 

Some were parents themselves, some weren't even thinking about it yet, some - okay, one, Suzy Cato - had made a career about educating children via the magical medium of song, dance and crafts on national television. 

What better group of people to grill with the hardest-to-answer questions that kids ask their parents?
