Mustahil is one of the woredas in the Somali Region of Ethiopia. Part of the Gode Zone, Mustahil is bordered on the south by Somalia, on the west by Kelafo, on the north by the Korahe Zone, on the east by Ferfer; the Shebelle River is flowing through this woreda. The major town in this woreda is Mustahīl; the average elevation in this woreda is 310 meters above sea level. As of 2008, Mustahil has any community roads. Mustahil was affected by the flash floods in Ethiopia during September 2006, the worst of any woreda in the Somali Region. An initial assessment by Ethiopian authorities found that 45,000 people were affected by the flooding; the October 2007 flooding affected 26,825 people in this woreda, displacing 6,000, devastating kebeles that had not been affected in the worst flooding of 2006. These kebeles included Budul, Jagi and Iman Ise. Moreover, grazing land, water sources and 5,630 hectares of crop land were destroyed by flood waters in Mustahil and Kelafo, which further exacerbated the fragile food security of the region.

Based on the 2007 Census conducted by the Central Statistical Agency of Ethiopia, this woreda has a total population of 49,315, of whom 26,668 are men and 22,647 women. While 6,174 or 12.52% are urban inhabitants, a further 7,332 or 14.87% are pastoralists. 99.45 % of the population said. This woreda is inhabited by Jidle and rer aw hasan, Xawaadle clans of the Somali people; the 1997 national census reported a total population for this woreda of 50,085, of whom 17,525 were men and 14,530 women. The largest ethnic group reported in Mustahil was the Somali 50,035

Fantastic Voyage is a 1966 American science-fiction film directed by Richard Fleischer and written by Harry Kleiner, based on a story by Otto Klement and Jerome Bixby. The film is about a submarine crew who are shrunk to microscopic size and venture into the body of an injured scientist to repair damage to his brain; the original story took place in the 19th century and was meant to be a Jules Verne-style adventure with a sense of wonder. Kleiner added a Cold War element; the film starred Stephen Boyd, Raquel Welch, Edmond O'Brien, Donald Pleasence, Arthur Kennedy. Bantam Books obtained the rights for a paperback novelization based on the screenplay and approached Isaac Asimov to write it; because the novelization was released six months before the movie, many people mistakenly believed that the film was based on Asimov's book. The movie inspired an animated television series; the United States and the Soviet Union have both developed technology that can miniaturize matter by shrinking individual atoms, but only for one hour.

Scientist Dr. Jan Benes, working behind the Iron Curtain, has figured out how to make the process work indefinitely. With the help of American intelligence agents, including agent Charles Grant, he escapes to the West, but an attempted assassination leaves him comatose with a blood clot in his brain that no surgery can remove from the outside. To save his life, agent Grant, pilot Captain Bill Owens, Dr. Michaels, surgeon Dr. Peter Duval, his assistant Cora Peterson are placed aboard a Navy submarine at the Combined Miniature Deterrent Forces facilities; the submarine, named Proteus, is miniaturized to "about the size of a microbe", injected into Benes. The team has 60 minutes to remove the clot; the crew faces many obstacles during the mission. An arteriovenous fistula forces them to detour through the heart, where cardiac arrest must be induced to avoid turbulence that would be strong enough to destroy Proteus. After an unexplained loss of oxygen, they must replenish their supply in the lungs.

They are forced to pass through the inner ear, requiring all outside personnel to make no noise, so as to prevent destructive shocks and Cora gets killed by antibodies. When they discover that the surgical laser, needed to destroy the clot is damaged, it becomes obvious that a saboteur is on the mission, they must cannibalize their wireless telegraph to repair the laser, making communication and guidance from outside impossible to get. By the time they reach the clot, they have only six minutes remaining to operate and exit the body. Before the mission, Grant had been briefed that Duval was the prime suspect as a potential surgical assassin, but as the mission progresses, he pieces the evidence together, near the end, instead begins to suspect Michaels. During the critical phase of the operation, Dr. Michaels knocks out Owens and takes control of Proteus, while the rest of the crew is outside for the operation. Duval removes the clot with the laser, but Michaels tries to crash the submarine into the clot area to kill Benes.

Grant fires the laser at the ship, causing it to crash. Michaels is killed when a white blood cell attacks and destroys Proteus. Grant saves Owens from the ship, they and the remaining crew swim to one of Benes's eyes, they escape through a tear duct seconds before returning to normal size. The original screenplay included a follow-up scene in which, because of brain damage caused by the submarine, Benes no longer remembers the formula for unlimited miniaturization. Surviving stills suggest that this scene was never used.

Richard Fleischer was assigned to Saul David to produce. Fleischer had studied medicine and human anatomy in college before choosing to be a movie director. Harry Kleiner was brought in to work on the script; the budget was set at $5 million. The budget went up to $6 million, $3 million of which went on the sets and $1 million on test footage; the film starred Stephen Boyd. It was the first role at Fox for Raquel Welch, put under contract to the studio after being spotted in a beauty contest by David's wife. For the technical and artistic elaboration of the subject, Fleischer asked for the collaboration of two people of the crew that he had worked with on the production of 20,000 Leagues Under the Sea, the film he directed for Walt Disney in 1954; the designer of the Nautilus from the Jules Verne adaptation, Harper Goff
