Mockumentaries

[EDIT] Thank you all so much, I didn't expect so many replies. You offered so many interesting recommendations, some I knew about, some are completely new to me, including even a couple from favorite directors. I saved the thread and will look for every single one you recommended. I have a super interesting cinephile year ahead!

Since some of you also mentioned some TV series, I take the occasion to mention my all time favorite mockumentary series, which I think is incredibly underrated: "Review with Forrest MacNeil". (An American remake of the original Australian edition that I still haven't watched).

Thank you all again!

I'm particularly fond of the genre mockumentary. Both really comedic, like Taika Waititi's What We Do in the Shadows, or more quirky - My all time favorite is the Italian documentary about an imaginary world cup match during WW2 "Il Mundial dimenticato - la vera incredibile storia dei Mondiali di Patagonia 1942".

Do you have any very good, witty mockumentary to recommend? From any country really - I know English, Italian, German and French, and will hopefully find subtitles for other languages.
