At his own company, Wally Burr Recording, he cast and voice directed many animated shows, such as Transformers and G.I. Joe. In 2001, Burr sold his recording studios.
Burr's direction style was very perfectionist, and he would often do many takes of a single line until he thought it had been nailed. This was often very exhausting for the voice actors, who often tell stories of Burr in interviews. They do agree that in the end, he created a quality product that satisfied everyone, and most think back on these sessions fondly despite their rigor.
