Finally managed to get to this after putting it off for two years. Think I got a fairly healthy and varied list going, and will hopefully discover some gems as we go along. The OG's list (as well as further rules) can be found HERE

The rules are as follows:
10 'Anniversary Films' (Release years end in an 8, excluding 2018)
6 countries
6 decades
6 films from before 1970
6 films from the following: Romero, Cronenberg, Clive Barker, Terence Fischer, Sergio Martino, Bill Lustig (mix-and-match, or all one)
2 flying things that kill you films
1 silent film as a tribute to A Quiet Place
1 aquatic menace film as a tribute to Meg
2 women directed films
1 inanimate object comes alive film
1 film with Barbara Crampton in it.

And 2 Tobe Hooper Films (There must ALWAYS be a Hooper film)
