Nippon no daikazoku Saiko! The Large family: Hôsô kinshi gekijôban

An enjoyable mockumentary with a compelling sub-plot mystery. Pay attention to the backgrounds, especially for things that seem a bit out of place or off. You'll be able to piece together to story well while watching this movie alone. However, if you want a fuller picture, this title is the English-speaking host version of the original Japanese-speaking host version- but do not be fooled! Despite identical titles, the Japanese-speaking mockumentary covers the plot that takes place chronologically before this movie. It's even hinted at by the family stating there was a documentary that featured them before while discussing the death photograph. (The original Japanese version was part of a larger series of "Banned From Broadcast" stories which do not all center around this family's plot.) It was a really relaxing but compelling viewing that I recommend.
