The south side of Gold Base is primarily used by Golden Era Productions, Scientology's in-house film studio. It includes a studio in the style of a Scottish castle, which was built in 1997–1998 at a cost of $10.8 million to serve as a production facility for the Church's training and promotional films and videos. The building, known as the "Cine Castle", replaced an earlier building known as "The Gym" which used to house Golden Era's shooting stage, make-up, costumes, camera, lighting, and set sound departments.
