Gothic fiction, which is largely known by the subgenre of Gothic horror, is a genre or mode of literature and film that combines fiction and horror, death, and at times romance.
 Its origin is attributed to English author Horace Walpole, with his 1764 novel "The Castle of Otranto", subtitled (in its second edition) "A Gothic Story".
 The effect of Gothic fiction feeds on a pleasing sort of terror, an extension of Romantic literary pleasures that were relatively new at the time of Walpole's novel.
 It originated in England in the second half of the 18th century where, following Walpole, it was further developed by Clara Reeve, Ann Radcliffe, William Thomas Beckford and Matthew Lewis.
 The genre had much success in the 19th century, as witnessed by Mary Shelley's "Frankenstein" and the works of Edgar Allan Poe.
 Another well known novel in this genre, dating from the late Victorian era, is Bram Stoker's "Dracula".
 The name "Gothic" refers to the (pseudo)-medieval buildings, emulating Gothic architecture, in which many of these stories take place.
 This extreme form of romanticism was very popular in England and Germany.
 The English Gothic novel also led to new novel types such as the German "Schauerroman" and the French "Georgia".
Edward Sorel (born Edward Schwartz, 26 March 1929, The Bronx) is an illustrator, caricaturist, cartoonist, graphic designer and author whose work is known for its storytelling, its left-liberal social commentary, its criticism of reactionary right-wing politics and organized religion.
 Formerly a regular contributor to "The Nation", "New York Magazine" and "The Atlantic", his work is today seen more frequently in "Vanity Fair".
 He has been hailed by "The New York Times" as "one of America's foremost political satirists".
 As a lifelong New Yorker, a large portion of his work interprets the life, culture and political events of New York City.
 There is also a large body of work which is nostalgic for the stars of 1930s and 1940s Hollywood when Sorel was a youth.
 Sorel is noted for his wavy pen-and-ink style, which he describes as "spontaneous direct drawing".

 The film was entered into the 15th Berlin International Film Festival.
