Great article. I was reading a Tippett interview yesterday and it mentioned the blur issue-so here in this decades old article he is giving a hint about the development of the Go motion process used in ESB, Dragonslayer and elsewhere. I didnt know he worked so closely with Danforth who did very realistic animation and some primitive blur effects for When Dinosaurs Ruled the Earth.

The chess scene was such an inventive little bit.

Those cut closeup shots are collector gold if they ever surface.

They say some people hate stop motion because the strobing effect is very noticeable to them. Rumor has it Spielberg is like that and wanted to avoid any stop motion on Jurassic Park until it became clear mechanical ones couldnt do it all. Then the cg experiments got better than expected results...

If you google for Pete Peterson animator there is some really impressive stop motion animation footage done in the 60s ---some for a movie never made called the Las Vegas Monster. Like Danforth he was a meticulous animator--and overcame the lack of motion blur to produce some remarkable and long lost animation.
