I was watching Walt Disney's Robin Hood (1973) tonight and in aw at all the work put into that film. The cast members are fantastic for each of the character voices. There's an emotion scene where the Sheriff of Nottingham barges in on Friar Tuck during a rainstorm and takes a last farthing from the poor box.
Friar Tuck tries to him to put it back but the Sheriff says, "I just doing my duty". The acting in the animation follows the voices perfectly bringing out emotion in the scene. These two character a large in size and the animator's literally throw their weight around. The way the characters move and act helps the story move along visually.
This above early color size concept piece is just as exciting to me as when I remember seeing it in 1973. I'm sure Milt Kahl and Wooly Reitherman had some challenges working this stuff out. It's a lot of work getting all of it done in a timely fashion.
