Gustav has been writing since he was a kid starting out with stories about spies and action heroes where he'd write and draw pictures in books he'd get from school. As a kid he was very into hockey and soccer so he'd make his own magazines with pictures and articles about players he liked.

Later, during his teenage years, an interest for film started to develop and he started making films with friends making up the script on the spot and putting the story together in editing which often worked out surprisingly well.

At 22 he moved to California and started the Film Production program at SBCC. He graduated from SBCC with degrees in Film Production and Theatre Arts in 2018 and his short film Stunning was screened at the 34th Santa Barbara International Film Festival at the beginning of 2019.

At the end of that same year, Gustav moved back to Sweden where he's now a represented actor by Schultzberg Agency in Stockholm. His first long form production as a writer, director and actor, a web series called Killin' It based on the short film of the same name is currently in post production.
