Ho Yay / The Man Who Knew Infinity

• It should be kept in mind that Hardy is actually gay (Shown in a few instances or talking points historically) and thus all the following should be considered parts of canon to get past the Moral Guardians
• The film opens with a voiceover by Hardy, wistfully reflecting on Ramanujan and their time spent together at Trinity college:
  Hardy: [while looking out of a rainy window] I owe more to him than to anyone else in the world, and my association with him is the one romantic incident of my life.
  [...] The difficulty for me, then, is not that I do not know enough about him, but that I know and feel too much.

• Hardy becomes very flustered and awkward in Ramanujan's presence, though that might be just as well due to his social awkwardness.

• He does do a lot of staring at Ramanujan and Ramanujan's general direction, though. His whole body language seems to indicate he is strangely drawn and attuned to Ramanujan's presence, which is a testament to how subtly Jeremy Irons created his performance.

• A fellow student hints at Hardy's romantic orientation and a possible infatuation with Ramanujan:
  Andrew Hartley: His father was a schoolteacher. Not exactly Trinity stock. Hardy's earned it on his own merits. It's probably why he's taken to you.
  Ramanujan: Does he have a wife?
  Andrew Hartley: No. He's married to his work, as they say. I suppose that means you now.

• When Ramanujan surprises Hardy in his private rooms to share a new mathematical discovery, one can briefly see Hardy had been writing romantic prose about a working class girl and a king. Considering the real Hardy had no interest in writing fictional prose, the only purpose this detail seems to serve is to highlight Hardy's secret romantic musings.

• When he learns that Ramanujan has a wife, Hardy looks shocked and dejected. He doesn't refer to the marriage beyond calling the wife her.

• Hardy and Ramanujan's last scene together is laden with emotion and subtext.
  • When Hardy tries to console Ramanujan over his wife, his words of consolation become a coincident admission of his own feelings:

    Hardy: There are no proofs nor underlying laws that can determine the outcome of matters of the heart. [melancholically adds] Of this I am ... sure.

  • When Ramanujan suggests that Hardy might find his own "matters of the heart" sometime in the near future, Hardy looks pained and mutters "perhaps".
  • Their parting hug is the stuff of slash-y fanfic. Ramanujan goes for the embrace, but before he can let go, Hardy draws him in just to hold him for a moment longer.
  • When they eventually make their goodbyes, Hardy looks like a piece of his soul was about to leave him.

• Hardy receives the good luck charm Ramanujan was wearing around his wrist in the letter informing him of the later's passing away in India, just as Ramanujan's wife had sent a hairband as token of her affection. He raises the charm to his lips, and begins to weep when he becomes aware of the letter's contents.
