Do you think that today (in the digital World), it would make sense to shoot a film in 35mm, in the right conditions?
Because, by Pierre's words, it seems so.

Nowadays some directors and many cinematographers working on big budget feature film productions still prefer to shoot on 35mm film (or sometimes even 65mm); they see advantages that still outweigh the capabilities of today's best digital cinema cameras. But in reality these differences in image quality are slight. Today's best professional digital cinema cameras now produce spectacular image quality and should continue to improve in the future. Digital cinema is now the norm, especially on productions that do not have huge production budgets.

I understand that under full control (and with the right badget -read, money-) you can do amazing movies/photos, but the size format is only 576i PAL. So I thought it had to be more blurry on my TV.

Nowadays, these old cinematographic masterpieces are re-scanned by the studios from the masters reels (when available) with the best current equipment and a whole process of digital correction of the defects left by the wear of time is meticulously applied, not to mention a re-calibration of all the colors and luminosity so as to well exploit the new digital supports. Such a 35mm film can easily be presented even in 4k without looking outdated.

Is it due to the Colour Process (Technicolor)? Because it is very sharp and the colour is very good.

Maybe the colour process, technicolor, is like the difference between music played on a "record" player instead of compressed mp3.

Every time I watch this movie I say: WOW!
Yes, it is the Alfred Hitchcock movie (Metro-Goldwyn-Mayer), then you can tell me it is impossible that it was ugly.
The Story is wonderful, the cuts, photography, light and colour are really good.
What about music by Bernard Herrmann? Wonderful!
And the great cast? I love Eva Marie Saint (as Eve Kendall). =)

There is also Martin Landau. Do you remember the "Space: 1999" sci-fi series? Listen its soundtrack: https://www.youtube.com/watch?v=1lDIlTZN2_8
Okay I am going Out Of Topic.

It is an old movie and today, at time I am writing, on TV channels in my country, it is broadcast in the 576i @25 fps format, but it seems really good on my tv/screen.
Why?
