A pressbook
is a piece of promotional material created and distributed by film
producers in order to market their films. Prior to 1980, most film
companies did their own promotion, and the pressbooks would be given to
exhibitors.
Pressbooks
generally contained information on the stars of the film, illustrations
of film posters or newspaper advertisements, notes that could be
planted in newspaper features or blurbs, ideas for exploitation
campaigns, and other promotional materials including ready-made film
reviews, souvenir-style giveaways and listings of various tie-ins with
the film.

The alternate titles include La isla de la muerte, Island of the Doomed and The Blood Suckers (UK title). The horror film is set on a remote island off the shore of an unidentified European country, in which the central character is a mad scientist (Cameron Mitchell) who creates hybrid trees that feed on human blood.
