There are basically two types of font :
A serif is the extra little 'Flick' at the end of each stroke of the letter.
Such as Clarendon, Rockwell and Courier. Usually are reffered to as a more traditional or Formal look.
In PEARL HARBOUR, the font being used is Palatino it is Serif Font. It is all in white colour and in capital letter. It might have references to a soldier in a row. Also the military clothing is very well organised as the letters are. As the soldiers are in their uniform, the title represents an order of neatness as the letters of the title are all in the same length in height. It is also intimidating, as soldiers are deemed to be.
In Rocky, the font being used is Franklin Gothic Heavy it is Sans Serif. It is big and bold and easy to read. It tells us that Rocky is not educated. He is simple, but hard working. The title suggests that Rocky is Brave & strong. Through the use of a very curved, smooth edged font it suggests that In the middle, he is soft, kind and caring. It helps the audience to empathise with Rocky and allow the audience to catch a glimpse into Rocky's mind type. As Rocky is of the lower class and Sans Serif is usually reffered to as a lower classed font, it seems be the perfect font to represent Rocky's personality.
