The legend that is Saul Bass!

Saul Bass started off as a graphic designer making symbols for ad campaigns. It wasn't when he was working with Otto making symbols for a film that they thought "Why not make it move" and his legacy went on. bass thought that the audience should feel involved in the very first frame. he also said that the title sequence to films "Is like the prologue to the action in the film, it gives you information but not too much that it spoils the film but enough to get the audience excited". his signature is lines over the creen and text which i think is very effective as it disorients you and again leaves room for the imagination.

Psycho:

The one minute fifty two seconds title sequence of Psycho was done so well that it is unforgettable.

the fast pace music sounds like someone running and that they are being chased and need to getaway quick. The music also has an icy chill to it which builds to the tension. The signature lines over the screen and the text disorients you and doesn't give too much of the plot of the film away.

North by North West:

Again there is lines over the screen but makes it seem map like and that maybe in the film the characters are also on the run. The music also connotes that the film could be fast paced.

In both of the title sequences Saul Bass leaves clues for the film which gets the audiences imagination working, however it doesn't let to much slide as that would ruin the film.
