One ... he regularly travels on the subway. There are quite a few videos of him on YouTube.
Two ... he gives up his seat without as much as batting and eyelid!
There is something about this man. He is reclusive and gives millions to charity. He also gives his time. He argues for fair pay for those who work on his films and he will give up his own fee, or a portion of it, to make it happen.
Now the fact he looks a bit like Mr Tink, or vice versa, might influence my thinking.
I think he has his demons. The death of his girlfriend not long after their stillborn baby must have affected him badly.
I think he's quoted as saying he has more money than he could ever need so giving it away makes sense. He's still as rich as all get out but at least he shares it round a bit.
