Delirium is 2019's winning entry in ScreenTest, NZ On Screen's school filmmaking competition. The short film explores the state of mind of Clark (Thomas van Tilborg), a schizophrenic who descends into dark places after he stops taking his medication. ScreenTest judge Paul Yates (Wellington Paranormal) called Delirium "an assured wee horror film by someone who clearly loves the horror genre", and praised it for making the viewer question the reality of what they were seeing. Tom Field wrote and directed the film as a year 13 student at Auckland's Kristin School.
