Good job. I was actually looking for Margery Sharp, the author of the nine Miss Bianca stories. I'll just let this question go.
You know, I had to rush to a class, and on the way I realized I was supposed to be looking for a person, not a film.

I saw Nick put "Watership Down" and that's a film or book, so I just put the correct film.

Also, my person post was invalid because I made an incorrect point in it; part of it is correct, the other half isn't so here is the revised question:
I am one of Walt Disney's famed "Nine Old Men"--the best hand drawn animators. My surname sounds much like the last name of two US presidents with the same last name (no relation). I share my first name with the character of a popular black and white tv show (where the character's name was in the title).
(It shouldn't take long to guess which of the nine I'm after....I would suspect most could come close to his last name at least.
