Neil Breen is an American filmmaker and actor. Since 2005, he has made six feature films in which he acts as director, writer, producer and lead star, while being in charge of most other key crew positions. He usually finances his films himself independently from his earnings as a professional architect, using amateur casts and crews.

Breen's works have garnered a cult following as "so bad it's good" films, often being singled out for their poor acting (notably from Breen), bizarre story and dialogue, offbeat editing and low-budget production values; his stories are typically psychological thrillers or science fiction with strong social commentary depicting lonely, tragic heroes in grandiose struggles against corrupt institutions.
