"The Best Exotic Marigold Hotel" does not only have a list of amazing actors. It is witty (if you like the British humor) and colorful, but at the same time rather emotional and at times even incredibly sad.
To come back to the actors: the majority of the protagonists are well known and once you've watched the movie it also becomes clear why that's the case. Their appearance seems authentic and no matter what kind of a character they represent, you can't help but take them to your heart.
And of course, India as a setting breathtaking. It is not trashy and romantic like in many other examples. You get a very diverse picture. You see its colors, the smiling people, the beautiful landscape and temples, but also its poverty and some people's hopelessness. It seems to give a picture of the real India (although I must admit, I've never been and therefore can't really judge).
You may cry just to start laughing a moment later. It shows life with all its faces.
So that you actually know what the movie is about, here's the trailer:
