George Lucas also had help on the script of empire from Leigh Brackett and Lawrence Kasdan. who helped him with the more emotional parts of the movie. by character driven i mean that the big huge fight on hoth was the beginning of the movie, and the duel on bespin cloud city was last but it was so powerful because of the I AM YOUR FATHER LINE. That it balances it out perfectly. It has been three years since the destruction of the death star and the victory of the rebellion but they have established a new base on hoth which is found by imperials.in the hoth scenes the cast traveled to Norway were it had its worst blizzard in 50 years and the sceane were luke runs away form the wampa ice monster was shot out of the back of a hotel for fear that the camera would freeze up, for the battle fo hoth that the rebels so sadly loose, members of the norwegian ski patrol were used as extras to fill space in the battle,also john Rtzenberg who played the role of cliff cathel on cheers was a rebel officer,the giant AT-ATS were created via stop motion animation and were set against a fake painted background! in a dream obi ones ghost visits luke,who tells him to learn from the great Jedi master yoda,luke does after the battle of hoth he escapes on his x wing after blowing up an atat. and Han solo and princess Leia frantically try to escape from the empire until they find a good hiding place on cloud city were they think they will be safe.The movie also takes time to go into the romantic relationship beetween han and leia before key family ties were established fans found it fun to speculate who would leia finnaly tie the knott with. But the empire has other plans he hires a group of ruthless bounty hunter to track down and capture the millennium falcon. only boba fett succeeds. this was boba fetts first live action appearance for many people recognized him as from the cartoon the god awful holiday special(see part one)
