Nils Elffors, a skilled and daring individual, was employed as an unit manager at Svenska Bio's studio on Lidingö, where he played a crucial role in the production of several films under the guidance of the renowned director Mauritz Stiller. In addition to his managerial responsibilities, Elffors also showcased his versatility by taking on minor acting roles, often portraying characters such as a valet.
As a pyrotechnic expert, Elffors was known for his fearlessness and exceptional skill in arranging elaborate and realistic special effects. He left an indelible mark on several films, including Vem dömer? (1922),Eld ombord (1923),Karl XII (1925),and Gösta Berlings saga (1924),where he masterfully orchestrated a range of dramatic and explosive sequences.
Tragically, Elffors' life was cut short during the production of Ödets man (1924),when he lost his life in a devastating explosion while attempting to supplement the film with a feature intended for international audiences. The scene, which involved a house being blown into the air, proved to be his final act, leaving behind a lasting legacy as a pioneering pyrotechnic expert in the early days of Swedish cinema.
