Saw this when I was 10 years old, scary!
Sorry, just reminiscing out loud!
I saw this film in a cinema in a small town in Mexico when I was 10 years old, and it's effect on me remains to this day. It scared me so much that night, I had to sleep with my parents, cover my neck with the quilt, etc.
A big hit at the time was No Milk Today by Hermans Hermits, and it forever remains the vampire song to me, lol.
This is the film that sparked off my interest in vampire films. I remember it's colour, how modern it seemed to us at the time, but overall the absolute fear i felt at 9.
Interestingly, it was being shown as a double-bill with a film called The Other (1972), and i just remember being scared out of my wits.
Funny how that intense fear scan remain with you (or the memory of it)
