Following World War II, a third theater was added featuring central staging. This welcome addition was adapted from a bungalow, a war emergency building. Plays were alternately scheduled into the three theaters, giving students opportunities for various stage experiences.

In 1959, the large auditorium was razed to make way for the new Administration Building, and in 1963 the Little Theater was torn down to make way for the new Theatre Building. The demise of the Little Theater was not without emotion as it had been the home of the Theater Department for over 32 years and many a student had enshrined it in memory. Before the leveling of the Little Theatre, the Engineering Annex was pressed into service as an "Interim Theater." Fortunately, for three and a half years it proved to be a most workable playhouse, and the training of students never slackened.

With the opening of the new Theatre Building, the Theater Department had, at last, a well-designed theatre building to accommodate all their activities and performances. This included a large proscenium theater, a smaller black box, and an intimate classroom stage. The large theatre was named the Camino, the black box, the Caminito, and the smallest, the Cameo. These names were given in honor of El Camino Real, which is thought to have passed nearby as it diagonally crossed through the campus. The road was created by the Franciscan Fathers as a route from one California mission to another, in this case from the Los Angeles Mission to the San Fernando Mission.
