I thought this was just fantastic. Robert Downey Jr plays Tony Stark, delivering a bionic arm built by Limbitless founder Albert Manero to a kid in need.

My favorite moment is about 1:08 in, when Alex (the kid) is asked, “Do you know who this is?” My sense is that Downey was a little worried that the whole Iron Man thing would be lost on him, that it would be a flop. It was not.
