Title: The Land Before Time X: The Great Longneck Migration Movie plot: Plagued by mysterious dreams, Littlefoot, his grandparents and all the other Longnecks depart the Great Valley, joining up with other Longneck herds as they travel to a single location; with Cera, Petrie, Spike, and Ducky (Littlefoot's friends) following the herds to an enormous crater, which they believe is the culmination of their journey. Littlefoot learns that long ago, that the Bright Circle (sun) was going to fall. However, a number of Longnecks came together to this very spot and raised up their necks, lifting the Circle back to where it had been. According to this creation myth, this stretching of their necks is how the Longnecks got their long necks. History is about to repeat itself, and so the Longnecks have returned to the crater in order to save the sun once more.However, another surprise is in store, as Littlefoot meets his father, Bron (Kiefer Sutherland), for the first time in his whole life. However, Bron isn't alone. Since parting from his now deceased wife (a song from The Land Before Time IV: Journey Through the Mists reveals that the concept of marriage does exist in The Land Before Time universe), he has become guardian to another young Brachiosaurus, Shorty, who becomes jealous of Littlefoot since Bron is spending more time with him. One dawn, Shorty tries to run away, but Littlefoot stops him and convinces him to rejoin the migration, he even goes as far as to suggest they become brothers. At this point, Littlefoot's friends arrive. Soon after, following a Sharptooth attack there is a furious battle. Bron, Pat, Grandpa and Grandma defeat the sharpteeth.Meanwhile the time comes for the Longnecks to save the sun again. Then they succeed and save the world. (However, what happened was, in fact, a solar eclipse; the Longnecks merely thought the sun was falling.)With their mission completed, the herds depart. Knowing their true places, Littlefoot tells Bron to take care of Shorty, and returns to the Valley with his friends and grandparents.

Title: Force 10 from Navarone Movie plot: In 1943, after their successful mission on the Greek island of Navarone, Major Keith Mallory (Robert Shaw) and Sergeant John Miller (Edward Fox) are sent to find and kill Nicolai. Originally thought to be a traitor who informed the Germans about Miller and Mallory during the Navarone mission, Nicolai is now known to be Colonel von Ingorslebon, a dedicated German spy believed to have infiltrated the Yugoslav Partisans as "Captain Lescovar" (Franco Nero). To get to Yugoslavia, the two men pair with "Force 10", an American sabotage unit, led by Colonel Mike Barnsby (Harrison Ford), which has its own mission there. To maximise security, Force 10 steals a Lancaster bomber from a British air base in Termoli, Italy, rather than requisitioning one; but they are spotted by Military Police MPs before they can take off. Weaver (Carl Weathers), a US Army sergeant under arrest by the MPs, joins with Force 10 and forces his way onto the plane. Barnsby and crew successfully "escape" Termoli, only to be shot down by Luftwaffe night fighters. Only Barnsby, Mallory, Miller, Weaver, and Force 10 member Doug Reynolds (Angus MacInnes) manage to escape the crippled plane. On the ground, the survivors run across a group they believe to be their allies, Communist Yugoslav Partisans, led by Captain Drazak (Richard Kiel). Force 10's rescuers are soon revealed to be collaborationist Chetniks (nationalist Serb guerrillas) under German control. The Germans take the team into custody but do not know their mission, so Mallory and Barnsby tell the commander, Major Schroeder (Michael Byrne), that they are criminals fleeing Allied authorities. To keep Schroeder from opening Miller's suitcase, which contains his special explosives, Mallory tells him that it contains a new wonder drug called "penicillin" which will spoil if exposed to air. By the next morning, the prisoners are told that Schroeder has opened the case, finding it full of firewood. Surprised, Mallory and Barnsby improvise an excuse, "admitting" they buried the samples. Schroeder...
