In 1967, at the age of 24, Andersson was admitted to the filmschool of the Swedist Film Institute, founded in 1963, run by Harry Schein and obviously influenced by Ingmar Bergman. Andersson went his own way and that resulted in him working on the famous Den vita sporten in the spring of 1968. In the summer, he worked as assistant director on Bo Widerberg’s Adalen 31 and in the autumn he directed Lördagen 5.10/Saturday October 5th.
