Lewis Andrew Schoenbrun (born September 21, 1958) is an American filmmaker and editor.

Schoenbrun became a fan of director Stanley Kubrick at age nine, when he watched the film 2001: A Space Odyssey. At eleven years old, Schoenbrun shot short films with his father's super 8 film camera, and received his own camera from his parents at the age of thirteen. In the 1970s, during his time at a university, he worked at a PBS station in Atlanta, Georgia, and later spent a year working with Tela Moving Images, a production company in Springfield, Massachusetts. During his time with the production company, he used a Moviola to edit a documentary film about a trip to Kenya, Africa that he went on with a group of aspiring astronomers.

In the late 1980s, Schoenbrun acted as an assistant editor on the films Mystic Pizza and UHF. After directing several direct-to-video films in the 2000s, Schoenbrun and a producer wanted to make a horror adaptation of the comic book hero Spider-Man, starring a female protagonist. In the summer of 2010, having instead chosen to create a parody film of the character the Hulk, Schoenbrun financed and directed the film The Amazing Bulk in Los Angeles, California. He remained in Los Angeles to work on the film's post-production and to shoot the film Aliens vs. Avatars.
