John R. Dilworth (b. 1963) is an animator who created and directed the "Ace & Avery" segments on Big Bag, followed by the "Noodles & Nedd" series on Sesame Street.
A New York-based artist, Dilworth began his career in advertising and subsequently worked with Michael Sporn and on the series Doug. He produced his own shorts in his spare-time, under the banner Stretch Films, and first gained widespread attention through his 1994 short film Dirdy Birdy (featured as part of the Spike & Mike touring festival). His 1995 short The Chicken from Outer Space received an Academy Award nomination and led directly to the Courage the Cowardly Dog series.
