    This was a really enjoyable biopic. It's nothing especially new. Similar ideas are explored more deeply in other oppressed/struggling people doing math movies, but it is a very enjoyable subgenre, what with films like Hidden Figures, The Imitation Game, and The Theory of Everything, and this was an addition to the subgenre that was really quite good. It is pretty moving and inspiring and is ultimately good enough for a good rating.

    The perks of waking up at 3AM super sick and not being able to go to work.

    I enjoyed this poignant biopic about young Indian mathematician Srinivasa Ramanujan, who discovered a genius for pure maths while working on his own in Madras.

    The film follows his journey to Trinity College, Cambridge, to work with professor G H Hardy, just as the First World War breaks out. But this dream come true soon turns sour, as an isolated Ramanujan becomes increasingly ill and depressed. Cambridge can rarely have looked so cold and bleak on film.

    Dev Patel and Jeremy Irons are excellent as Ramanujan and Hardy, and there's a good supporting cast including Toby Jones. Unfortunately, Ramanujan's wife and mother don't get much screen time and aren't properly developed as characters.

    I learned of this movie as a trailer shown before the previous movie I just watched; Love & Friendship I didn't really like that movie but the one GOOD thing about watching it was learning about this one. The Man Who Knew Infinity is the kind of historical bio-pic / drama that I am always on the lookout and very rarely see. At least very rarely seen, done as well as this. Jeremy Irons is his consistently awesome self..and does his superb best in the movie but the stand out star for me has got to be Dev Patel who shines. The star who most would know from the Best Exotic Marigold Hotel movies plays a deeply moving portrayal of S. Ramanujan a mathematical genius struggling to be seen despite the bigoted refusal by the academics of the time. The friendship between Patel's character and that of Irons was heartfelt and genuine... This is definitely a movie that should be seen and enjoyed.

    Why I watched this one? Saw a trailer that looked promising.

    What is this one about? The story of the life and academic career of the pioneer Indian mathematician, Srinivasa Ramanujan, and his friendship with his mentor, Professor G.H. Hardy.

    My thoughts on this one? The good stuff: I enjoyed the performances of Dev Patel and Jeremy Irons. Actually I am beginning to really appreciate the acting skills of Patel....who by the way might soon be an Oscar nominated actor soon....if you believe the buzz on his Lion movie that is coming out. I also liked the story....and I appreciated getting to know more about Ramanujan. The drawback of the movie is it seemed to follow the blueprint of so many other other words the movie is onecliche after another. Final thought: A good but far from great movie. The best trivia I picked up from the movie is that Ramanujan is mentioned in Good Will Hunting!
