Korean horror films have been around since the early years of Korean cinema, however, it was not until the late 1990s that the genre began to experience a renewal.
 Many of the Korean horror films tend to focus on the suffering and the anguish of characters rather than focus on the explicit "blood and guts" aspect of horror.
 Korean horror features many of the same motifs, themes, and imagery as Japanese horror.
James Lawrence (October 1, 1781 – June 4, 1813) was an American naval officer.
 During the War of 1812, he commanded USS "Chesapeake" in a single-ship action against HMS "Shannon" commanded by Philip Broke.
 He is probably best known today for his last words or "" "Don't give up the ship!"
, which is still a popular naval battle cry, and which was invoked by Oliver Hazard Perry's personal battle flag, adopted to commemorate his dead friend.

 "The Ghost") is a 2004 South Korean horror film.

The City of the Dead, or Cairo Necropolis ("Qarafa, el-Arafa"), is an Islamic necropolis and cemetery below the Mokattam Hills in southeastern Cairo, Egypt.
 The people of Cairo, the Cairenes, and most Egyptians, call it "el'arafa" (trans.
 'the cemetery').
 It is a 4 mi long (north-south) dense grid of tomb and mausoleum structures, where some people live and work amongst the dead.
 Some reside here to be near ancestors, of recent to ancient lineage.
 Some live here after being forced from central Cairo due to urban renewal demolitions and urbanization pressures, that increased from the Gamal Abdel Nasser era in the 1950s and forward.
 Other residents immigrated in from the agricultural countryside, looking for work — an example of rural to urban migration in an LEDC (least economically developed country).
 The poorest live in the City of the Dead slum, and Manshiyat Naser, which is also known as Garbage City, a center of recycling and reuse Zabbaleen vendors.

Fiction in the '70s brought a return of old-fashioned storytelling, especially with Erich Segal's "Love Story".
 The early seventies also saw the decline of previously well-respected writers, such as Saul Bellow and Peter De Vries, both of whom released poorly received novels at the start of the decade, but rebounded critically as the decade wore on.
 Racism remained a key literary subject.
 John Updike emerged as a major literary figure with his 1971 novel "Rabbit Redux".
 Reflections of the 1960s experience also found roots in the literature of the decade through the works of Joyce Carol Oates and Wright Morris.
 With the rising cost of hardcover books and the increasing readership of "genre fiction", the paperback became a popular medium.
 Criminal non-fiction also became a popular topic.
 Irreverence and satire, typified in Kurt Vonnegut's "Breakfast of Champions", were common literary elements.
 The horror genre also emerged, and by the late seventies Stephen King had become one of the most popular novelists in America, a coveted position he maintained in the following decade.
