I can't recall seeing a CG film with the effect, but any of the earlier ones printed on film certainly had grain when they were in theaters originally. They just use the digital source files for restoration so you can't see it that way today.
>>125195793Originally they were going to produce a second feature called "East of the Sun, West of the Moon". Unfortunately production was cancelled because of the animator's strike in 1982 and union changes.
Ironically Dragon's Lair ended up making them much more money than NIMH did at the time.
