Sebasthian "Basse" Wilnerzon Thörn, born on October 17, 1992, is a Swedish filmmaker, editor, cameraman, and writer. He is one of the founding members of Monte Fjanton and has been a driving force behind the team’s creative output. Basse began his filmmaking journey with the production of Tahkorerna I – Maktens Stenar, which sparked the creation of Monte Fjanton a few years later. Together with Felix, he leads the team, balancing epic war films with Monty Python-style humor, intense horror films with training montages, and comedic series such as Felix Recenserar and Basses rätt i skafferiet. As the team’s lead editor and cameraman, Basse works primarily behind the camera and at the editing desk, though he has also appeared in a number of films, including roles in the TAL series and Day of the Not-So Dead Living. He is responsible for much of Monte Fjanton’s content, including the Morden i Tyringe series, and has written and directed films such as Geti 2. In addition to his work in film, Basse is an author. He has written the cookbook Basses rätt i skafferiet, based on his cooking series, as well as the fantasy novel Sången från underjorden.
