Se7en - Font and Colour

-White font which has connotations of purity and innocence creates juxtaposition wth the genre of the film

-The credit it small which draws attention into what is happening in the scene rather than the actual credits

-San serif font keeps it simplistic and easier to read

San serif font can also signify formality 

Se7en - Placement and Suitability 

-Uses the rule of thirds, to make it easier for the audience to see and acknowledge 

The credit it small which draws attention into what is happening in the scene rather than the actual credits

Suitability is good because the font is slightly blurred, which creates slight confusion and mystery
