Title: Mo' Better Blues Movie plot: The film begins with a scene set in Brooklyn, New York in 1969. A group of four boys walk up to Bleek Gilliam's brownstone and ask him to come out and play baseball with them. Bleek's mother insists that he continue his trumpet lesson, to his chagrin. His father becomes concerned that Bleek will grow up to be a sissy, and a family argument ensues. In the end, Bleek continues playing his trumpet, and his friends go away. The next scene brings us to the present (over twenty years later), with an adult Bleek (Denzel Washington) performing on the trumpet at a busy nightclub with his jazz band, The Bleek Quintet (Jeff "Tain" Watts, Wesley Snipes, Giancarlo Esposito and Bill Nunn). Giant (Spike Lee, one of his boyhood friends from the previous scene and current manager of Bleek's band), is waiting in the wings, and advises him to stop allowing his saxophone player Shadow Henderson (Snipes) to grandstand with long solos. The next morning Bleek wakes up with his girlfriend, Indigo Downes (Joie Lee). She leaves to go to class, while he meets his father by the Brooklyn Bridge for a game of catch, telling him that while he does like Indigo, he likes other women too and is not ready to make a commitment. Later in the day while he is practicing his trumpet, another woman named Clarke Bentancourt (Cynda Williams) visits him. She suggests he fire Giant as his manager; he suggests that they make love (which he refers to as "mo' better"). She bites his lip and he becomes upset about it, saying, "I make my living with my lips", as he examines the bleeding bottom lip. Giant is with his bookie, betting on baseball. Then he goes to the nightclub and argues with the doormen about what time to let the patrons into the club. He meets Bleek inside with the rest of the band, except for the pianist, Left Hand Lacey (Esposito), who arrives late with his French girlfriend and is scolded by Giant. Later Giant goes to the club owners' office, points out how busy the club has been since Bleek and his band began playing there, and...???

Title: Silent Running Movie plot: Silent Running takes place in the not-so-distant future, at a time in which Earth's plant life has been decimated. Only a few specimens of flora have been preserved, and are currently in space in a fleet of orbiting greenhouses.Freeman Lowell (played by Bruce Dern) is the main character, one of four extraterrestrial forest rangers aboard the Valley Forge, one of the 2,000 metre-long green house freighters. He is passionately dedicated to preserving the orbiting forests and their natural inhabitants, and eventual returning them to Earth for reforestation of his now-barren planet more so than his crewmates, whose main priority seems to be returning to Earth after their one-year deployment to space.The main conflict comes when Lowell and his crew are ordered to destroy the orbiting greenhouses and redeploy the freighters to commercial service. Lowell decides to disobey orders and save the forests he has worked so hard to preserve.Lowell's crewmates manage to jettison and detonate four of the six greenhouse domes on the Valley Forge. Lowell kills one of his crewmates in a struggle to save the two remaining domes, during which he seriously injures his leg. He then manages to trap the other two crewmen in the other remaining dome, which he then jettisons and destroys.With help from the ship's three robots, Lowell feigns a premature dome detonation to fool his superiors, then alters the orbit of the Valley Forge , redirecting it towards Saturn in an attempt to preserve the last forest dome. Injured and alone with three robots, Lowell programs them to perform surgery on his leg.Still in communication with the rest of the fleet, Lowell is informed that the Valley Forge is on a collision course with Saturn's rings, and there is nothing he can do to stop the catastrophic event. The ship will likely be destroyed. With communications failing due to the distance now between the Valley Forge and the rest of the fleet, the ship passes through the rings of Saturn. While the three robots are outside the ship on maintenance...

Question: Who is the very rich book collector? Title: The Ninth Gate Movie plot: Balkan shows his 17th-century copy of The Nine Gates to Corso. Dean Corso (Johnny Depp), a New York City rare book dealer, makes his living conning people into selling him valuable antique books for a low price, and then re-selling them to private collectors. Corso meets with wealthy book collector Boris Balkan (Frank Langella), who has recently acquired a copy of the (fictional) book The Nine Gates of the Kingdom of Shadows by 17th-century author Aristide Torchia, one of only three extant copies. The book is an adaptation of one written by the Devil himself and purportedly contains the means to summon the Devil and acquire invincibility and immortality. Balkan believes two of the copies are forgeries. He hires Corso to check all three, and acquire the legitimate one by any means necessary. Balkan's copy was acquired from Andrew Telfer (Willy Holt), who killed himself soon after. Telfer's widow Liana (Lena Olin) seduces Corso, in a failed attempt to get the book back. Meanwhile, Corso leaves the book for safekeeping with bookseller Bernie Rothstein (James Russo), who is then murdered; his corpse is found posed like an engraving in The Nine Gates. Corso travels to Toledo, Spain. The Ceniza brothers, book restorers, show him that three of the engravings are signed "LCF". Corso deduces that Lucifer himself designed and cut them. Corso travels to Sintra, Portugal, to compare Victor Fargas' (Jack Taylor) copy of the book to Balkan's. To Corso's surprise, he discovers that the signature "LCF" is found in three different engravings, which vary in small but significant details from the images in the Balkan copy. The next morning, a mysterious young woman (identified only as "the Girl") (Emmanuelle Seigner) who appears to have been shadowing Corso since Balkan hired him, awakens Corso and leads him to Fargas' house. He finds the old man murdered and the "LCF"-signed engravings ripped out of that copy. In Paris, Corso visits the Baroness Kessler (Barbara Jefford), who owns the third copy. At first the Baroness refuses...
