Babel is a name of a tower once upon a time.
According to bible, during that time, men built Babel the Tower as higher as they can, with an ambitiuos desire to reach the heaven. God was very angry when seeing on this. Humans are too arrogant to comparing with God. God had separated the humans into different places, skin colours, races and languages.

Babel is also a movie's name. The movie scenes are cohesively sparked among the anxious husband & wife whom travelling and desperate brothers in Morocco, unhappy disabled young lady in Japan and unfortunate baby sitter in US.

Joke, is a very sad joke...
