Generate a question that has the following answer: Herbert & Herbert for the following movie plot: Private detective Sam Grunion (Groucho Marx) has been searching for the extremely valuable Royal Romanoff diamonds for eleven years, and his investigation leads him to a troupe of struggling performers, led by Mike Johnson (Paul Valentine), who are trying to put on a musical revue called Love Happy. Grunion notes that the impoverished young dancers would starve were it not for the sweet, silent Harpo (Harpo Marx), at Herbert & Herbert, a gourmet food shop that also trafficks in stolen diamonds. Harpo kindly helps ladies with their shopping bags, all the while pilfering their groceries and stuffing them in the pockets of his long trench coat. When the elegant Madame Egelichi (Ilona Massey) arrives, store manager Lefty Throckmorton (Melville Cooper) tells her that "the sardines" have come in. Harpo sneaks into the basement and watches as Lefty lovingly unpacks a sardine can marked with a Maltese cross, and swipes the can from Lefty's pocket, replacing it with an unmarked one. Madame Egelichi, who has gone through eight husbands in three months in her quest for the Romanoff diamonds, is furious when Lefty produces the wrong can. When Lefty remembers seeing Harpo in the basement, she orders him to call the police and offer a $1,000 reward for his capture. At the theater, meanwhile, unemployed entertainer Faustino the Great (Chico Marx) asks Mike for a job as a mind-reader, and when Faustino's clever improvisation stops the show's backer, Mr. Lyons (Leon Belasco), from repossessing the scenery, Mike gratefully hires him. Harpo, who is secretly in love with dancer Maggie Phillips (Vera-Ellen), Mike's girl friend, gives her the sardine can, and she says she will eat them tomorrow. A policeman sees Harpo inside the theater and brings him to Madame Egelichi, who turns Harpo over to her henchmen, Alphonse (Raymond Burr) and Hannibal (Bruce Gordon) Zoto. After three days of interrogation, Harpo still refuses to talk, and when he is left alone, he calls Faustino at the theater, using the bike horn he carries in his...

Q: Generate a question that has the following answer: Less than a mile. for the following movie plot: A privately owned luxury Boeing 747-100, Stevens' Flight 23, flies invited guests to an estate in Palm Beach, Florida, owned by wealthy philanthropist Philip Stevens, who also owns the jetliner. Valuable artwork from Stevens's private collection is also on board the jetliner, to be eventually displayed in his new museum. Such a collection motivates a group of thieves led by co-pilot Bob Chambers to hijack the aircraft. Once Captain Don Gallagher leaves the cockpit and is knocked unconscious, the hijackers' plans go into action. A sleeping gas, which one of the hijackers secretly installed before the flight, is released into the cabin and the passengers lose consciousness. Knocking out the flight engineer, Chambers moves forward with the hijacking, and Stevens' Flight 23 "disappears" into the Bermuda Triangle. Descending to virtual wave-top altitude, Flight 23 heads into a fog bank, reducing visibility to less than a mile. Minutes later, a large offshore drilling platform emerges from the haze, Flight 23 heading straight for it at nearly 600 knots. Chambers pulls back on the yoke in a banking left turn, but an engine clips the derrick and catches fire. Chambers immediately hits the fire extinguishing button, and the flames are momentarily extinguished. Because the aircraft is at such a low altitude, the sudden loss of airspeed threatens to stall the airplane. As the engine reignites, Chambers is forced to use another fire suppression bottle. But by this time, the aircraft stall alarm is activated and the aircraft's tail hits the water. All the passengers wake up, and realizing what is happening, most panic. Chambers is able to pull up, but the plane's right wing hits the water again. The plane lifts into the air for a moment, then hits the water. Because of the hard impact, the plane becomes grounded in the ocean and begins to sink. The ocean floor is above the crush depth of the fuselage. Many of the passengers are injured, some seriously. Two of the would-be thieves die in the initial crash. Banker is in the...

Generate a question that has the following answer: Maggie's birthday party for the following movie plot: Sam Cahill (Tobey Maguire) and Tommy Cahill (Jake Gyllenhaal) are brothers. A Marine captain about to embark on his fourth tour of duty, Sam is a steadfast family man married to his high school sweetheart, Grace (Natalie Portman), with whom he has two young daughters, Isabelle and Maggie (Bailee Madison, Taylor Grace Geare). The film opens with Tommy being released from jail for armed robbery, not long before Sam departs for Afghanistan in October, 2007. Soon news comes that Sam's helicopter has crashed over the water, killing all of the Marines aboard. In reality, he and a hometown friend, Private Joe Willis (Patrick Flueger), have been taken prisoner in a mountain village. With Sam "gone", Tommy attempts to redeem himself in the eyes of his family by wrangling old friends to help with kitchen repairs for Grace and the kids. Grace slowly sheds her previous resentment towards her brother-in-law. As months pass, Grace and Tommy bond over their mutual mourning, culminating in a passionate fireside kiss. They regret it afterward, and do not take this attraction any further, though Tommy continues to win the favor of his nieces. Meanwhile, Sam and Joe are abused and tortured by terrorists, forced to make videotaped dismissals of the military and their mission, though only Joe cracks. The captors eventually deem him useless and force Sam, at gunpoint, to beat Joe to death with a lead pipe. He does so and reacts angrily. Sometime later, Sam is rescued. Sam returns home, clearly traumatized by his experience. He drifts through encounters in a cold, paranoid daze, refuses to explain to his family what happened while he was in Afghanistan, and lies to Joe's widow that he does not know how Joe died. He also believes Tommy and Grace had a sexual relationship in his absence. During Maggie's birthday party, a resentful and jealous Isabelle claims that Sam's paranoid assumptions are true: that Tommy and Grace slept together. Sam becomes enraged, destroying the newly remodeled kitchen with a crow bar and pulling a pistol on...
