News Gothic is a bit closer for the top one. Compare the C and S.

Wouldn't Nimbus Sans Bold Extended be a better match for the bottom sample? Strangely, Nimbus's daddy, Helvetica, is much farther away.

From the book Alfred Hitchcock and the Making of Psycho, by Stephen Rebello.

Postproduction
Adler, who previously had worked with Bass on the title sequences of Vertigo and North by Northwest before tackling Psycho, explained how it was done: .... I did the title, Psycho, in Venus Bold Extended and got two reverse photostats made.... For the other big titles, like 'Directed by Alfred Hitchcock', I used News Gothic Bold typeface and we did the same three-cut technique as for the title of the movie.

The thing is that the S and the C of PSYCHO don't match with the Venus Bold Extended, they are closer in the shapes to the Extrabold weight though.
Did they modify the S and C they had?
Different cut of Venus from another foundry?
A little lack of memory by Adler?
Is it the Psycho Week?

It must be.
