Donald Virgil Bluth is an American filmmaker, animator, video game designer and author. He came to prominence working for Walt Disney Productions before creating his own film studio in the early 1980s. Bluth is best known for directing the animated films The Secret of NIMH, An American Tail, The Land Before Time, All Dogs Go to Heaven, and Anastasia, and for his involvement in the well-known Laserdisc game Dragon's Lair. Don Bluth Productions hired many animators away from Disney, and Bluth's films were a major competitor to Disney in the 1980s, leading up to the Disney Renaissance.
