Okay, this book is not for entertainment. Its a story about India mathematician S. Ramanujan who do not even has schooling knowledge but still able to solve hardest math problem in seconds. It was a mystery how he was able to do so. Professor G. H. Hardy was also mesmerized by his ability.
Two main character of this movie is S. Ramanujan and Professor G. H. Hardy which is played by Dev Patel and Jeremy Irons respectively. Both has done there job tremendously well.
The cinematography is well, as usual, did by Hollywood. Every scene seem like realistic and has a different kind of energy in it.
