The combination of the document author's ancillary texts (poster and magazine) and main product (trailer) for the film "Fostered" are effective at promoting and attracting an audience. The ancillary texts use imagery and content from the trailer to generate interest and intrigue viewers. Specifically, the poster features a black and white image of the protagonists from a key scene in the trailer where a character films events. Color schemes, fonts, and costumes are consistently used across the ancillary texts and trailer to establish tone and symbolism while following genre conventions. The goal is to preview the film's storyline just enough to create hype and demand without revealing too much.
