"We got 'horror', and I thought good, we've done a fair few horrors beforehand.
"Script writing was done via Zoom, and as a group we thought others might make a horror film about a pandemic [since we are in the middle of Covid-19 pandemic]. But we didn't want to do that."
"Art can elevate us, and take us beyond our personal circumstances, and as a group that's what we wanted to do," said Mr Corbett.
Without giving too much away, Mr Corbett said their entry is a horror film about a bunch of misfits who perform a sacrifice.
From the technical point of view, every person had to film themselves and then they sent the film to Mr Corbett who shrunk the people, combined the shots and set them against a background of his own backyard. He said it was especially hard, because no one had a professional camera, apart from him.
"The film was shot on cellphones, webcams and home computers!"
While talking about the script, the group decided they wanted the film to look like there was more than one person in the shot and to use illusion where possible. For instance, one person would kick the ball from the left side in their garden, and then another person would receive a ball from the right side in their garden.
"It's like the most spastic filmmaking I have ever done! But it [the film] is so good."
Mr Corbett says the 48 Hour film festival embodies what is beautiful about making a film in a short time.
"And you just take the limitations and run with it."
Some outdoor filming for last years entry Extra Time at a home in Sunset St led to a thumbs down in the Taupō & Tūrangi Weekender, with one onlooker apparently confusing it with an adult movie in production.
This year's film requirements saw Mr Corbett rush outside while wearing his boxer shorts.
"My wife gets a call from the neighbour, asking 'Is it that time of year again?'"
