Australian Domenic Pace, 9, acting out a scene on the steps of the Sydney Opera House on Thursday, as he is granted his wish of becoming a superhero. Sydney police staged the elaborate event, with Hollywood star Robert Downey Jr, who has played Iron Man in many movies, tweeting his support. Domenic, who has battled cystic fibrosis throughout his life, has long idolised Marvel superhero Iron Man and expressed his wish to be "Iron Boy". The Make-A-Wish Foundation granted his dream to fight crime in Australia's biggest city.
