Robert Downey Jr may not be a real superhero, but he came to the rescue of a little boy who burst into tears when he met him.
Heather Denno took her 18-month-old son Jaxson to watch filming for new movie The Judge, starring Robert, in her hometown of Sunderland in Massachusetts.
The Iron Man star spotted the little boy and went over to say hello.
Heather Denno told Jaxson that the actor was Iron Man.
Confused because of the lack of the trademark metallic red and gold suit, Jaxson burst into tears.
The actor put a comforting hand on the boy and calmed him down.
Heather Denno told the Boston Globe that Robert was "sweet and nurturing," and she could tell he's a dad.
