Clip of where it is Brilliant-
It'd be great for a comparitive study in the genre of horror, especially looking at use of sound or literary adaptations.
You can see a great number of horror tropes here-
The film being in black and white gives it a better depth of field than a colour film (this is 1961, it could have been made in colour, although most British films in this era were blakc and white as it was cheaper and also seen as more artistic)
