American Gangster Trailer

The American Gangster trailer has many close ups of action shots - implying it is an action film. The voice of the trailer is a line from the actual film and fits in well with the shots playing along with it. However, the non-diegetic music playing over the trailer is not a convention of the action genre, but later on in the trailer the music turns solemn and sad which implies that something sinister is going on which reaffirms the action genre. The conversations that are chosen out of the film to feature in the trailer are also sinister conversations and news coverage talking about drugs being the public enemy number however, right after that shot there is an advertisement of drugs by Denzel's character talking about his merchandise - Cohen's moral panic theory would suggest that this trailer may influence people to take drugs, making the media the folk devil in which to blame people taking drugs on.
