As I said before, Lucas is the original creator of the Star Wars, and Star Wars looks like the son of Lucas。He has not only the original idea, also is a truly pioneer in film special effects. Spielberg is different story. He is a very typical successful American capitalist and diretor, who likes to exploit, especially the writers。 ET AI Jurassic Park,Schindler's List are all from other writers。 From another aspect, ET AI Jurassic Park and Schindler's List are very good movies, but all of them can not be compared with Star Wars, which is one of the most influential masterpieces in the mass culture of US history。
一般来说,70年代以后美国电影导演tier 1就仨 Francis coppola george lucas martin scorsese 界基本上是公论,不光是好莱坞电影业,这三人也造就了电影专业UCLA NYU USC三足鼎立的局面 woody allen和spielberg属于第二集团。有人觉得woody allen比spielberg牛都不奇怪,不过说spielberg比lucas牛就比较奇怪了。
