Gorgeous Swede Sonja Lindgren only has three credits to her name, but it doesn't matter, for she changed the course of skinematic history with her debut, which also happens to be her nude debut and one of filmdom's moist notorious features. It was I Am Curious (Blue) (1968), and blue it is. The sequel to the infamous I Am Curious (Yellow) (1967) finds Sonja playing herself in her birthday suit, right down to her hairy patch, with another full-frontal female. They frolic by a pond. You'll frolic in your pants.
