Q: Generate a question that has the following answer: Chris O'Donnell for the following movie plot: Callow youth D'Artagnan (Walter Abel) sets off from Gascony for Paris, armed with his father's sword, an old horse and a letter of introduction to his godfather, Captain de Treville (Lumsden Hare), commander of the King's Musketeers. Along the way, he attempts to rescue Milady de Winter (Margot Grahame) from highwaymen, but it turns out she came to meet their leader, the Count de Rochefort (Ian Keith). When Rochefort insults D'Artagnan, the latter insists on a duel. Instead, Rochefort has his men knock D'Artagnan out, while he blackmails Lady de Winter into helping him in his plot to seize power. Upon reaching Paris, D'Artagnan is dismayed to learn from de Treville that he must serve two years as a cadet or perform "extraordinary deeds of valor" before he can become a Musketeer. Then he spots Rochefort on the street. In his haste to confront his enemy, D'Artagnan unintentionally insults three Musketeers: Athos (Paul Lukas), Porthos (Moroni Olsen), and Aramis (Onslow Stevens) in turn, agreeing each time to a duel. When his opponents arrive at the appointed place, they are amused to discover they are all engaged to cross swords with the same man. However, Cardinal Richelieu's Guards try to arrest the Musketeers for dueling. D'Artagnan joins the outnumbered trio and acquits himself well.

Q: Generate a question that has the following answer: MacNeil, Sanders, and Shimada for the following movie plot: Off the coast of Alaska, oceanographer Emma MacNeil (Deborah Gibson) is studying the migration patterns of whales aboard an experimental submarine she took without permission from her employer. Meanwhile, a military helicopter drops experimental sonar transmitters into the water, causing a pod of whales to go out of control and start ramming a nearby glacier. In the chaos, the helicopter crashes into the glacier, and the combined damage breaks the glacier open, thawing two hibernating, prehistoric creatures. MacNeil narrowly avoids destruction as, unknown to her, a giant shark and octopus are freed. Some time later, a drilling platform off the coast of Japan is attacked by the octopus, which has tentacles large enough to wrap around the entire structure. After returning to Point Dume, California, MacNeil investigates the corpse of a beached whale covered with many bloody wounds. Her employer Dick Richie (Mark Hengst) believes them to be from a tanker propeller, but MacNeil insists they appear to be from a creature. Later, she extracts what appears to be a shark's tooth from one of the wounds. Elsewhere, the huge shark leaps tens of thousands of feet into the air from the ocean and attacks a commercial aircraft, forcing it to crash into the water. A review board convenes and fires MacNeil from the oceanographic institute for stealing the submarine. She brings the shark tooth to her old professor, former U.S. Navy pilot Lamar Sanders (Sean Lawlor), who believes it belonged to a Megalodon, an enormous species of shark believed to have become extinct 1.5 million years ago. The duo is visited by Dr. Seiji Shimada (Vic Chao), a Japanese scientist trying to determine what attacked the drilling platform. The three review a videotape recorded during MacNeil's submarine voyage, finding images of both the megalodon and a gigantic octopus. MacNeil reflects on the polar ice caps melting due to man-made global warming, and wonders if the creatures are mankind's "comeuppance". Meanwhile, a U.S. "naval destroyer"...
