Gay Theme?

I haven't seen it, but another poster wrote this:

The film is directed superbly. The story is told clearly and directly. The gay subtext of trainer lusting after fighter is handled frankly, sincerely and with a bittersweet truth. It exposes a sad case in our society, straight or gay, that older people are denied physical love at every level.

It's about an elderly gay man who coaches a straight boxer and helps him to become a success.

We also learn that the elder man was the victim of homophobia when he was young, keeping him from reaching his goals as a young boxer.
