Dear John

Dear John is from the romance genre, this is clear throughout the trailer due to the generic, narrative, technical and audio codes.

Within the trailer, text showing what the authors have written This proves their track record and will create high expectations for this film.

The main characters of the film are played by Channing Tatum and Amanda Seyfried - who are both young and attractive. Having good looking actors is typical of the romance genre.
Moreover, the fact that the main characters form a heterosexual relationship is also very typical of the genre.
The fact that the male is the instigator of the relationship - by jumping off the pier to retrieve her bag - reinforces gender roles. It is common for the male within the relationship to be portrayed as heroic, and for the female to act as a sort of damsel in distress, and needing the man to help her.

An audio code within the trailer is the non-diegetic music, a pop music sound track is used which is very typical of the genre. Furthermore, the song lyrics 'miles from where you are' relates to the plot. It represents the binary opposition of the couple being located on different sides of the world. As well as reinforcing the plot, this code can show the common theme throughout the romance genre that love can overcome every obstacle. Elaborating on this, the music shifts when they kiss, signifying that the relationship has become serious. Supporting this, the pace of editing increases as the relationship intensifies.
