The great graphic designer Saul Bass (1920-1996) though having created many well-known logotypes and posters, is mostly know and remembered for his work with movie title sequences (IMDb). This is a collection of the few I found on YouTube. My thanks to those who uploaded them. If you find more or upload more please let me know.
"My initial thoughts about what a title can do was to set mood and the prime underlying core of the film's story, to express the story in some metaphorical way. I saw the title as a way of conditioning the audience, so that when the film actually began, viewers would already have an emotional resonance with it."Check this site out for great screenshots from other of Saul Bass' title sequences and this one for screenshots of other great titles.
