A:
david harald vilgot sjöman -lrb- 2 december 1924 -- 9 april 2006 -rrb- was a swedish writer and film director .his films deal with controversial issues of social class , morality , and sexual taboos , combining the emotionally tortured characters of ingmar bergman with the avant garde style of the french new wave .he is best known as the director of the films `` 491 '' -lrb- 1964 -rrb- , `` i am curious -lrb- yellow -rrb- '' -lrb- in swedish , `` jag är nyfiken - gul '' -rrb- -lrb- 1967 -rrb- , and `` i am curious -lrb- blue -rrb- '' -lrb- `` jag är nyfiken - blå '' -rrb- -lrb- 1968 -rrb- , which stretched the boundaries of acceptability of what could then be shown on film , deliberately treating their subjects in a provocative and explicit manner .
