Growth in business
After working on The Ren & Stimpy Show, many other shows requested the assistance of Rough Draft Korea in animation and ink & paint. In 1992, Rough Draft Studios had produced animation for its first feature film, FernGully: The Last Rainforest. In the same year, the studio began producing animation for The Simpsons and then for Beavis and Butt-Head in 1993. Also in 1993, Gregg's brother Scott Vanzo was brought on board. Rough Draft Korea quickly built a strong portfolio in the animation business with shows like their first series produced outside of South Korea, The Maxx in 1995, which was nominated for an Annie Award. Claudia Katz, who had joined Rough Draft Studios in 1994 to produce The Maxx, and Rich Moore, joining in 1995 after having worked with Gregg on The Simpsons, completed the core of a Rough Draft Studios which would help "drive the cartoon boom of the late ‘90s". It was also in 1995 that Rough Draft Studios moved to Glendale, California, where they enjoyed further success. Peter Avanzino, who was acquainted with the studio during his career, joined in 1998 and stayed a director at the studio.
