You know how it is: you get on the train, an old man starts perving at you, maybe he sings a song, maybe he gets his tongue out, but the disturbing thing is that he looks strangely familiar.

That's because he's Uncle Hank. And he's been riding Darren Aronofsky's subway for years.

At first, I recognised the man in Black Swan as being vaguely like the bloke from Pi, but thought it was just a coincidence. Then I started to re-watch Aronofsky's back catalogue and realised he was a proper recurring character. Allow me to introduce you to Darren Aronofsky's favourite uncle.
