For the fonts, we looked through (too) many pages of different styles. Dafont is a website which allows you to preview your word(s) using different fonts and compare them. It was really useful for us to see which would suit our opening better.
As simple as it seems, it was actually a tough decision. In the end, we decided that the fonts we are going to use for the credits and our production company name are going to be classical. This is mostly because we want the audience to concentrate on the actual story and not other details.
Regarding the title of the movie, we chose a really bold, eye-popping font, as the narration will end by the time the title will appear. We agreed on this because we want the viewers to remember our film.
