This is a very unique movie - there is hardly anything out there that comes close to it. It has some elements of a comedy to it, but most of all I would consider it a brilliant essay on modern life. Every time I watched this masterpiece I felt strange, but also amused and well educated. This is certainly not a movie if you want to be entertained by gunfire or hot chicks - it’s more like looking into a magic mirror and discover your own world from a new perspective. It also has it’s own speed and melody.
Here are some scenes on YouTube: overall videos, Trailer and Tati arrives at Corporation.
