The Psychotronic Encyclopedia of Film - X, Y, & Z
Films listed in the "XY" and "Z" sections of The Psychotronic Encyclopedia of Film by Michael Weldon (Ballantine Books, 1983), the single most influential book in my film book library. It is almost thirty years since purchasing my first copy, and I am still trying to see all of the films in it. The book is a must if you love monster, sci-fi, rock 'n' roll, beach, disaster and horror films of all types. Some really great photo and poster selections as well (all in glorious black and white).
These are the films on this list which are still missing from the database (titles updated 01-04-14):
The Young Swingers (1963)
Your Money or Your Wife (1960)
You've Got to Be Smart (1967)
