input question: Generate a question that has the following answer: swimming for the following movie plot: In the opening scene, a woman named Ruth is walking her dog on Los Angeles, California's Venice Beach, and is suddenly pulled under the sand of the deserted beach by an unseen force. The woman's screams for help are heard by Harry Caulder, a harbor patrol officer who is swimming nearby. Harry reports Ruth's disappearance to two LAPD detectives, Royko and Piantadosi, who claim that without a body, there is little they can do. The next day, Ruth's estranged daughter, Catherine, arrives from San Francisco after Harry calls her regarding her mother's disappearance. Meanwhile, the mysterious and crazed Mrs. Selden, who resides in an abandoned section of the Santa Monica Amusement Pier, witnesses the attack and disappearance (and others throughout the film), but does not come forward. That night, while staying in Ruth's house, Catherine hears Ruth's dog barking on the beach near the location where Ruth disappeared. Catherine investigates and finds the dog beheaded, near a small sinkhole. Royko and Piantadosi, as well as Harry, are called to the scene, but police pathologist Dr. Dimitrious cannot accurately determine a cause of death for the dog. Royko and Piantadosi believe it to be the work of a serial killer, due to reports of other disappearances over the past few months. The next morning, a teenage girl is buried in the sand at the beach, and begins screaming. Her friends pull her out of the sand, only to see that her legs have been injured from an attack by an unseen creature. The police, led by Captain Pearson, begin an investigation by digging up various sections of the beach at night, but find nothing. The next morning, people visit the beach, which the local media have dubbed "blood beach". The following night, Harry's co-worker Hoagy is closing up the harbor patrol office for the night when his girlfriend ventures under the pier to investigate a noise and is assaulted by a man. After being knocked to the ground by the girl, the would-be-rapist is attacked by the unseen creature, which castrates him. An...???

input question: Generate a question that has the following answer: Libby for the following movie plot: Short-order cook Frank Darbo recalls his only two good memories from a disappointing life: marrying his wife, Sarah, and an incident in which he directed a police officer to catch a purse snatcher. Frank immortalizes these two events in a pair of crayon drawings that he hangs on his wall for inspiration. Sarah, a recovering addict, leaves Frank for Jacques, a charismatic strip club owner who gets her hooked on drugs. Frank sinks into depression, where he has a vision in which he is touched by the finger of God and meets the Holy Avenger, a superhero from a public-access television show, who tells Frank that God has chosen him for a very special purpose. Frank believes that God has chosen him to become a superhero and goes to a local comic book store for inspiration. His claim that he is designing a new superhero is met with enthusiastic appreciation from the store clerk, Libby. Frank creates a superhero costume and assumes the identity of "The Crimson Bolt." Armed with a pipe wrench, he begins to fight crime by delivering savage beatings to various rulebreakers, ranging from drug dealers and child molesters to a man who cuts in line at the movies. The Crimson Bolt soon becomes a media sensation. Initially, the media view him as a violent psychopath, but he begins to gain public appreciation after the criminal backgrounds of many of his victims come to light. Frank later attempts to rescue Sarah, but Jacques' thugs recognize him under the costume and shoot him in the leg as he flees. A wounded Frank goes to Libby for help. Libby cajoles Frank into letting her become the Crimson Bolt's "kid sidekick," christening herself "Boltie" and designing a costume. She proves to be even more unhinged than Frank, using her superhero guise to nearly kill a man who possibly vandalized her friend's car. Frank decides to let her go, but changes his mind when Libby rescues him from some of Jacques' thugs at a gas station. Libby soon becomes enamored with Frank, but her advances are turned down as Frank insists that he is still...???

input question: Generate a question that has the following answer: Terrians for the following movie plot: Mala (Evan Rachel Wood) and her friend Senn (Justin Long) are young alien creatures who live on Terra, a planet from a star system in the Milky Way. Terra is a peaceful planet of alien creatures who have a rich semi-advanced culture. One day a large, mysterious object blocks the Terrian sun, piquing the Terrians' interest. However, since the Terrian culture bans the development of new technologies, such as telescopes, without the approval of the ruling council, none of the inhabitants are able to get a closer look at the huge object in their sky. Mala, who is inventive and headstrong, goes against the rules of her community and creates a telescope, which she takes out into the dark empty area outside the Terrian city and uses to view the object and witnesses smaller objects coming from the large object that turn out to be incoming scout spaceships. She returns to the city to find that the scout spaceships have already started abducting Terrians (who willingly offer themselves to the scout spaceships mistaking them as their new "gods"). After Mala's own father, Roven (Dennis Quaid) is abducted she goads a ship into tailing her and lures it into a trap, which causes it to crash. Afterward, she saves the life of the pilot, revealed to be a human, an officer named Lieutenant Jim Stanton (Luke Wilson). After his personal robot assistant named Giddy (David Cross) warns Mala that Stanton will die without a supply of oxygen (which the Terrian atmosphere does not contain), she creates an oxygen generator and fills a tent with air containing oxygen so that Jim can breathe, and eventually convinces Giddy to teach her human language. The Robot informs Mala that the mysterious object is a generation ship called The Ark, containing humans from Earth. Centuries beforehand, both Mars and Venus were terraformed by humans and colonized. But 200 years later, the two planets demanded independence from Earth, which the Earth government refused to grant them due to the high demand of resources from the two colonies. The dispute...???
