This is an older film, from 1980, but it is still very relevant to issues of globalization today. The God’s Must be Crazy opens in the Kalahari Desert in the remote village of Sho. The Sho people find a Coke bottle and it results in serious conflicts among the Sho. Ultimately, these discords cause a breakdown in social order of their society.
This film suggests -in an exaggerated circumstance of course- the unexpected ramifications of global culture. The message of the film is that transmitting culture globally has the potential to impact cultures negatively.

In addition, to this film I would also like to suggest this book called Video Night in Kathmandu: And Other Reports from the Not-So-Far East by Pico Iyer, which discusses how American culture is impacting other cultures.
