Who are the best animators in the motion picture industry?

In my opinion best animators are Hayao Miyazaki and Katsuhiro Otomo,and best mangaka Katsuhiro Otomo

They are great filmmakers but certainly not the best "animators". I would have to say James Baxter (Belle in Beauty and the Beast, Quasimodo in Hunchback among many) is one of the best. Glen Keane (Ariel, Little Mermaid and Beast, Beauty and the Beast, etc.) Sergio Pablos, Mark Henn, Andreas Deja are some of the others. In the past you have the Nine Old Men of Disney that are the pioneers of great animation.
