I am not sure about the post you are referring to, but it reminds me a movie called The Gods Must be Crazy. Here is a synopsis from Amazon.com:
South African director Jamie Uys caught lightning in a bottle with The Gods Must Be Crazy--a Coke bottle, to be specific. This slaphappy collection of goofy pratfalls and culture-clash gags became an enormous international smash, and made a sort of star out of the Bushman selected to play the central role, the completely ingratiating N!Xau. He plays a man, unaware of white culture, who finds a Coca-Cola bottle in the Kalahari (dropped by a passing pilot) and promptly has his life turned around by this mystical object. The movie looks slipshod and even amateurish at times, yet its attitude is so bubbly it's hard to resist. Proving that physical comedy remains a true international language, millions of moviegoers around the world drank it up. --Robert Horton
