This studio produced the short film Banjo the Woodpile Cat, the feature film The Secret of NIMH, a brief animation sequence in the musical Xanadu, and the video games Dragon's Lair and Space Ace. Bluth then co-founded Sullivan Bluth Studios with American businessman Gary Goldman, John Pomeroy and Morris Sullivan in 1985.
