The name of the Gym is said to have come from the cover story used by Scientology to conceal its activities at the base. According to Marc Headley, who worked on the base for fifteen years; "the permit to build the studio was applied for under the guise of a 'basketball gym.' Any and all references to the building were to be specified as the 'Gym'." The Gym still stands and is now reported to be used as a small (supplementary) studio and special effects facility.
