There's an awful lot and it seems I have some catching up to do!

Nice try Nos!
It's "Spirits of Death" though (see my previous post).
Seems you also have some cleaning up to do. ;)
I guess if you're not familiar with the titles it's not so easy.

The Crimes of the Black (Cat).

I own quite a lot of those and know of most of the ones I don't. Some are completely new to me so I've done my best to edit the list correctly.

I'll have a go since you've fixed most of them. :thumb: ;)

Only a few minor adjustments,good job Nos! :thumb:

Now comes the hard part: trying to watch and/or own every one of them!

Some of them aren"t available on dvd.
If you want I'll make a list of titles that are available on (English friendly) dvd?

Wow i only own 53 of those titles on dvd.

You seem to have missed Death walks at Midnight and The Sister of Ursula

Are those in the video Demdike?

Sorry, didn't watch the video, thought you were just doing a comprehensive list. I read back a few pages to try and find out what the list signified before i stuck my oar in. :)
