La Mexicaine De Perforation (The Mexican Consolidated Drilling Authority) is a subdivision of a French group called the UX (for Urban eXperiment). They provide clandestine artistic events.
In September 2004, french police discovered an underground movie theatre run by La Mexicaine De Perforation. The makeshift theatre contained a movie screen, a well stocked bar, and a kitchen. Telephones and electricity were brought in from an unknown location. Movie titles ranging from 1950s classics to modern thrillers were also discovered. When the police returned for a formal investigation, all the equipment had disappeared—all that was left was a note on the floor reading, "Ne cherchez pas" ("Do not search").
