According to Park, he started writing scary stories and screenplays from a young age, before moving into acting and producing.

Throughout his twenties, Park had roles in various films and commercials, including Stop/Eject by fellow British filmmaker Neil Oseman,[5] in which he appeared alongside The Worst Witch star Georgina Sherrington.

In 2016, he released his first short horror, Vicious,[7] which centres around a young woman who returns home one night to find the front door unlocked.

In 2017, Park released his second short film, Still, which tells the story of an artist terrorised by a dark figure with a bag over its head.

Safety measures the production crew followed included mask wearing and regular COVID tests and temperature checks.
