In this gorgeous video by Jurjen Versteeg you can learn about the history of the title sequence in a nutshell.

[The] film refers to elements such as the cut and shifted characters of Saul Bass’ Psycho title, the colored circles of Maurice Binder’s design for Dr. No and the contemporary designs of Kyle Cooper and Danny Yount.

I am a great admirer of Saul Bass’ work. His title sequence for Hitchcock’s Vertigo taught me how to appreciate all the minute details of film as art, how to draw bridge-lines between the eye and the mind’s eye. Like in all great art, nothing is wanting, nothing superfluous. Not even nothing, fadeout. His title sequence for North by Northwest is another one of my favourites, enriched additionally with Hitchcock’s trademark signature appearance. Spot the Hitchcock!
