There are many movies and books out showing an interaction between people from different cultures, their contrary map of the world if you want. They can be a great source for anyone interested in studying or teaching intercultural communication.
Though it is not reality, they still open eyes to some differences and lead us back to real life and being more thoughtful dealing with other people - also people from the same culture.
Enjoy the inspiration and please personal message me if you can add to the list.
