'Avengers: Age of Ultron' Star Robert Downey Jr Tweets Boy Who Had 'Rough Day'; 'You Made My Day & My Year'

Not only does he play superheroes in the movies, but Robert Downey, Jr. has become a superhero to a young boy in real life. The actor had quite an interesting exchange with his young fan on Twitter Wednesday night.

It all started when a mother, Kathy Ellis, sent a Twitter message to the actor asking him a favor, reports CBS News. Celebrities like Downey, Jr. undoubtedly get all sorts of request on their social media account but he couldn't ignore this one.

Ellis wrote, "@RobertDowneyJr It would make my son Aidan's day if you could re tweet "hi." As you can see he has had a rough day," and showed a picture of the boy with a gash on his face. She probably didn't expect that the "Iron Man" actor would reply. However, he casually asked, addressing Aidan, "@trips034me Aidan, what's up? Tell me everything," and had a few more exchanges with his fan on Twitter.

The boy gave him an account of what happened to his face, to which the superstar advised putting ice on it because it will leave a mark. He closed his message with, "Nice to meet u, in a soc media sorta way," and Aidan couldn't be any happier. He told Downey, Jr., "@RobertDowneyJr you made my day and my year. Thanks for talking to me." The exchange was short but very personal.

Following the exchange, many netizens praised the actor for the way he treated a young fan. Only a few hours before that, Downey, Jr. was in a foul mood as it was reported on several news sites, including Entertainment Weekly, that he walked out on an interview.

The Hollywood star was in a press junket for his latest film, "Avengers: Age of Ultron," but he got offended when the interviewer asked him questions that alluded to his past as a drug addict and his time in jail. His reps did not comment regarding the incident.

Meanwhile, Downey, Jr. made another splash with the kids when he surprised them during an exclusive presentation of his movie in Times Square Thursday night. The event was for charity, according to NY Daily News, and Downey, Jr. went to introduce "Avengers: Age of Ultron" to the young audience.

"To see all these motivated youngsters and have the sense that they're actually capable and invested in doing things that are uplifting for the community is just great," said the actor in the Daily News story.
