I saw "Being There" when it first came out, in a theater in Copenhagen Denmark. A good crowd was present, based on Sellers' star power etc. These are folks who all speak English very well. The film was in English with Danish subtitles.
I was the ONLY person in the theater who laughed even ONCE. The humor just did not translate one iota to the Danish mindset. It was really strange, to be the only person to "get" the humor, out of a hundred intelligent, English-speaking viewers.
I'll never forget how odd that experience was.
Im also a fan of Monty Python and South Park among others.
