The journalist character Em Bellishing, played by Jessica Mutch-Mackay, is totally fictional, but Jessica is in fact a real Journalist, she is the political reporter for TV One News and the spot where she filmed her scene is their actual reporting location and camera person Scarlett in the film, is one of Jessica's regular camera operators for TV One News.
The film's Prime Ministers office is over the road from the real Parliament buildings, its actually visible through the window in the background. But this building used was actually the former NZ Parliament before the iconic Beehive building was built.
The film was partly filmed in the actual Parliament Buildings of New Zealand. The crew had a 2 hour window early on Sunday morning to film all the interior shots.
