This tactic emanates from the romantic feelings Charlie harbors for Sam and his importance to the storyline. The other main visual effect used to enhance the trailer is the use of “title slides”. These slides are used to reveal things to the audience, for example when it starts the first one used says "Charlie never stood out until he found friends who let him in", you learn also the names of his new friends through the use of these slides. . Slides like these are a very productive advertising tool as the viewer must read the slide and therefore mentally and fully engage with the content.
