Who is Robert Downey Jr?

Many years ago, when my son Justin was about 14 years old, his friend Jr came to me and said, "Don't you think that Justin looks like Robert Downey, Jr." and, I said, "Who's Robert Downey, Jr.?" He mentioned a movie called Restoration. It seems they (my son and Jr) were watching this movie and Jr decided that Justin looked a lot like Robert Downey, Jr. So I took the movie restoration out of the local library and watched it. I saw what Jr was talking about. Justin did look like Robert Downey, Jr. I thought,"Oh, why couldn't my son be a famous movie star." Then about two weeks later I had the radio on in my kitchen and was listening to the news. It said that Robert Downey, Jr. had been arrested (yet again) for drug use. Right there at that moment I thanked G-d that my son was not a famous movie star. But at the same time (probably because of the physical resemblance he shared with my son) my motherly heart went out to Robert Downey, Jr. and I felt sadness for his troubled situation. Needless to say, that I was now aware of who Robert Downey, Jr. was. I have seen many of his movies. I am happy that he has finally settled down and is happily married (again the mother in me).
