Hollywood superstar Robert Downey Jr, who plays Ironman in Avengers: Infinity War, surprised 37 children from Make-Wish-Foundation in Singapore. He walked in casually and made them take the Avengers oath. This event was organized by Make-A-Wish Singapore, The Walt Disney Company South-East Asia and Marina Bay Sands during the promotions of the upcoming superhero film Avengers: Infinity War, which releases in India on April 27.
