[Q]: Generate a question that has the following answer: a harbor patrol officer 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: Please answer the following: Generate a question that has the following answer: Marshall and Caldwell for the following movie plot: American and Russian Special Forces capture General Ivan Radek (Jurgen Prochnow), the dictator of a rogue terrorist regime in Kazakhstan that possessed stolen Soviet nuclear weapons, threatening to start a new Cold War. Three weeks after the mission, U.S. President James Marshall (Harrison Ford) attends a diplomatic dinner in Moscow, during which he praises the capture and insists the United States will no longer negotiate with terrorists. Marshall and his entourage, including his wife Grace (Wendy Crewson) and daughter Alice (Liesel Matthews), and several of his Cabinet and advisers, prepare to return to the United States on Air Force One. In addition, a number of members of the press corps have been invited aboard, including Russian terrorists and Radek loyalists disguised as journalists led by Ivan Korshunov (Gary Oldman). After takeoff, Secret Service agent Gibbs (Xander Berkeley), who has been a mole, enables Korshunov and his men to obtain weapons and storm the plane, killing many of the other agents and military personnel before taking the civilians hostage. Marshall is raced to an escape pod in the cargo hold while pursued by Korshunov's men but they are too late to capture him as the pod is ejected. Instead, Korshunov storms the cockpit and prevents the plane from making an emergency landing at Ramstein Air Force Base in Germany, and secures Grace and Alice separately from the other hostages. Several F-15s escort Air Force One as Korshunov has it piloted towards Radek-loyal airspace. Unknown to Korshunov, Marshall, a Vietnam War veteran and Medal of Honor recipient, has remained hidden in the cargo hold instead of using the pod and begins to observe the loyalists using his military training. Marshall manages to kill some of Korshunov's men and then uses a satellite phone to make contact with his Vice President Kathryn Bennett (Glenn Close), letting his staff know he is alive. Korshunov, believing that only a rogue Secret Service agent is in the cargo hold, contacts Bennett and demands Radek's...

output: Who directs the plan back to friendly airspace?

Problem: Generate a question that has the following answer: an antique gun for the following movie plot: The story follows Jerry Welbach (Brad Pitt) as he travels through Mexico to find a valuable antique gun, The Mexican, and smuggle it into the United States. Five years earlier, Welbach had caused a traffic accident in which he hit the car of local mobster Arnold Margolese (Gene Hackman), who was jailed for five years after the police searched his car following the crash, finding someone tied up in his trunk. In compensation for the jail time, Welbach has been sent on various errands by Margolese's prickly second-in-command, Bernie Nayman (Bob Balaban). Retrieving the gun will be his final errand. Welbach has a girlfriend, Samantha (Julia Roberts), with whom he argues constantly and who leaves Jerry prior to the trip over his lack of commitment to their relationship. Jerry arrives in Mexico and makes his way to pick up Beck (David Krumholtz), the Margolese employee now in possession of the gun. There, a drunken Beck tells Jerry about the gun's history as a suicide weapon used as part of a jilted love-triangle between a woman, a nobleman, and the son of the gunsmith who forged the weapon, as well as its curse to misfire. Jerry helps Beck to his car, only for the man to be killed by celebratory gunfire from a nearby festival. Panicked but determined, Jerry buries the body and then calls Bernie to report on the situation, only for his vehicle to be stolen while he makes the call, the gun still inside. Jerry briefly has an uncooperative donkey as transportation to follow the thief, then buys an old, damaged truck. Meanwhile, Samantha gets kidnapped by a hit man named Leroy (James Gandolfini), who tells her that Jerry hired him to make sure she is safe from anybody that wants her dead. It is then revealed that Leroy is gay, which doesn't bother Samantha. They pick up a postal worker named Frank (Michael Cerveris), who then has a relationship with Leroy. Another hitman follows them to Las Vegas and kills Frank to make it look like a suicide. Leroy kills him in an act of vengeance, and flees with Samantha. Jerry...
