Oh dear... the synopsis says pretty much everything you need to know about this Finnish film from the early 80s. I cannot believe nearly 50,000 people saw this one in the theatres when it was released.
"Pi pi pil... Pilleri" fits the bill of a classic B movie: the plot is thin and ridiculous, the acting is interesting to say the least, the film looks cheap and shots are visually boring, and there is full frontal nudity. The runtime is also padded with extra scenes, such as a striptease bit, a can-can dance, the ending party, and what feels like 10 minutes of a guy skiing in a snowy forest.
Most Finns also recognize two of the characters from their roles in children's films and television series, so if you want to ruin your childhood, check out how Allu "Rölli" Tuppurainen and the voice actor for Moominpappa star in a "sexy" film.
Highly recommended if you like bad films as this one is right up there with titles like "Ponterosa" and "Levottomat 3" as the "best of the worst" of modern Finnish cinema. Steer clear if you do not like bad movies.
