Pop Skull is a 2007 American film directed, co-produced, and edited by Adam Wingard, who co-wrote the screenplay with Lane Hughes and E. L. Katz.

It is primarily regarded as a horror film but has been noted for incorporating elements of genres such as drama, psychedelic, romance, and thriller.

Daniel, a young Mexican-American pill addict living in Alabama, finds that his attempts to cope with his day-to-day trials collide with the increasing influence of the murderous and displaced spirits that inhabit his home.

In 2003, Wingard approached Hughes with the idea of making a semi-autobiographical film about a recent breakup.

LA Splash said Hughes gave "a truly magnetic Manson vibe the entire time" which allowed Wingard "to make great use of the extreme close-up".
