This is a wonderful interview with the late Tissa David.
It’s a rather long video (approx. 1 hour 45 minutes) but large portions of are of playbacks from her animated commercial work. The real gems in my estimation are where she relates how she discovered animation and eventually settled in the USA and (of course) her tips on animation. Her love of animation shines throughout.
Tissa worked with Grim Natwick and both Tissa and Grim had considerable influence on Richard Williams approach to animation. Of course Williams has gone on to spread many of the lessons he learned with the current generation of animators (both traditional and CG) via his book ‘The Animator’s Survival Kit’.
If you are an artist/animator and haven’t heard of Tissa you should watch this video.
