Lock Out is a 1973 full-length film by Spanish artist and director Antoni Padrós.

The recently restored film is an allegory of political oppression under Francisco Franco, with a plot alternating between narrative sequences and dream-like moments styled after the Spanish avant garde. Padros employs a range of musical forms including opera, scores, and choreography to underscore a plot featuring a group of dropouts living in a junkyard, who try to re-integrate with "The System" as represented by a party. Anarchy and absurdism are the stylistic veils covering this harsh criticism of the Francoist State.
