Disney's Hollywood Studios pays homage to classic Hollywood by recreating famous Hollywood landmarks, using billboards to convey messages from 1920's Hollywood and by placing Hollywood movie making references throughout. Once such reference is the mention of the International Brotherhood Of Second Assistant Directors.
During the height of Hollywood popularity nepotism (the act of hiring family members whether they were qualified or not) ran rampant. Often the "not so talented" family member would be given the fancy title of Second Assistant Director and the responsibility of standing behind the director while holding their coffee for them.
The catch phase on the sign stating: "We're Standing Behind You!" was a reference to the job duties of the Family Member - Second Assistant Directors.
Note: Second Assistant Director is a real job title for people in the film and television industry today. The mention about the humorous job duties of the "not so talented" family member is not intended to belittle the duties of the present day Second Assistant Directors.
