The combination of the main documentary product and ancillary texts like a newspaper advertisement and double-page spread is effective. Similar fonts and images are used across the different media, creating visual common ground and helping the audience recognize the documentary's subject. This establishes a relationship between the viewers and the documentary's subject before they watch it. Taken together, the ancillary texts and documentary successfully reflect the intended mood and philosophy and work to promote and advertise the documentary through intertextuality.
