The two fonts used in both movies are very different from each other and also both imply two very different genres/ type of movie. The font used in Pearl Harbor is very soft but also distinct, which could suggest the movie is a drama with a hint of romance. Another thing that noticed was that the font uses serifs. The use of serifs in font carries with it the implication that what ever it used for is going to be from the past; which relates to this movie seen as it is set in the past.
The font used in rocky is very bold, thick, heavy and altogether very masculine. When the viewer sees font like this, it automatically brings two genres to mind Action or "Shoot em up". The reason why I think this font as chosen is because it does a great job of connotating the genre/ what the movie is about, to its audience.
