Kiwi filmmaker Jason Lei Howden began production on Guns Akimbo in Auckland on Saturday, with Samara Weaving joining Daniel Radcliffe in the cast.
The movie is described as an "adrenaline-fuelled, balls-to-the-wall original action comedy" and is the second feature for the writer/director following his hit 2015 horror comedy Deathgasm.
"I am massively excited to be here in Auckland starting filming on Guns Akimbo," Radcliffe says.
"Jason Lei Howden has written a brilliant and delightfully insane script, and working with him as director and alongside the fantastic Samara Weaving to bring it to life is going to be a lot of fun.
"If you see me around Auckland looking very worse for wear and covered in blood and bruises, don't worry - this is probably for filming."
Weaving, 26, is a former Home and Away star who was last seen on the big screen in award season darling Three Billboards Outside Ebbing, Missouri.
Guns Akimbo will follow an ordinary man whose mundane existence is turned upside-down when he finds himself enrolled in a dark social media movement that forces strangers to fight in a city-wide game of death, live-streamed worldwide to a fanatical audience.
Howden told Flicks.co.nz he hopes Guns Akimbo beats the 'high watermark' set by acclaimed modern action movie John Wick.
On social media, the filmmaker has teased fans with glimpses of a rocket launcher and an American muscle car in tweets about the movie.
Guns Akimbo will be filmed in Munich, Germany as well as New Zealand.
