Gregg Turkington is an Australian-American entertainer, actor, musician, and writer who performs as Neil Hamburger, a stand-up comedian persona he developed in the 1990s. Alongside Tim Heidecker, Turkington also stars as a fictionalized version of himself on the comedic web series On Cinema (2011–present). In addition, he formed one-half of the band Zip Code Rapists and has collaborated on numerous projects with musicians including Trey Spruance (Mr. Bungle, Secret Chiefs 3).
In the 1990s, Turkington ran an independent label, Amarillo Records, which distributed his original albums and albums of other artists from the San Francisco punk scene. In 2015, he starred as a variant of the Neil Hamburger character for the feature-length drama film Entertainment, directed by Rick Alverson, and subsequently gave his first interviews as himself instead of an assumed persona. Turkington also was a regular voice actor on the Disney XD series Gravity Falls, and had a supporting part in the 2015 film Ant-Man by Marvel Studios.
