I think few young people today understand the importance of this man's career, especially in the early days. He was a consumate showman, even in the early days. He was a child actor who people identified with, and almost always came across on his films as positive. Walt Disney would have known him as a child actor, and I believe that his personna and performances in the Andy Hardy series, with Judy Garland, and other projects may well have help form Walt's expectations of his teens and young adults in the MMC serials and other projects as Walt ventured into more live action. What I mean is that Mickey Rooney set the standard for young actors of the day -- positive and energetic, yet a gentleman, on camera.
He later famously had 8 wives, and also later spoke to congress about abuse of the elderly; but overall he never really stopped taking roles that were uplifting and respectful.
Check out
Boys Town if you have never seen it (a true story of a priest who founded an orphanage in Nebraska), or any of the
Andy Hardy movies. Or
The Black Stallion for later work.
All worth seeing.

It includes an episode of the great old TV game show,
What's My Line, where celebrities usually tried to guess the line of work of the guest, but where every so often another celebrity appeared and they had to be blindfolded and guess who it is. Of course this time it is Mr. Rooney. It is fun to watch. A throw back to a simpler time.
