《神都龙王》虽然晚《通天帝国》四年上映,但故事早在拍《通天帝国》的时候就有了。《狄仁杰之神都龙王》最初筹拍的时候叫《狄仁杰前传》。因为从时间上来看,它讲的是狄仁杰更年轻时的故事,早于《狄仁杰之通天帝国》。但徐克不太喜欢这个叫法,他觉得两个故事不要强调前后,因为它们同时诞生。当初差点就先拍《狄仁杰之神都龙王》,如果这样,后拍的《狄仁杰之通天帝国》就成了《狄仁杰后传》。 “God is the Dragon King” Although late “Heaven” was released in four years, but the story as early as the film “Heavenly Empire” when there. “Di Renjie God Dragon King” when the initial filming is called “Di Renjie prequel.” Because from the time point of view, it tells Di Renjie younger story, earlier than “Di Renjie Heaven’s Empire.” However, Tsui Hark did not like this name, and he felt that the two stories should not emphasize the context because they were born at the same time. Almost the first shot “Di Renjie God Dragon King”, if so, after the filming of “Di Renjie Heaven’s Empire” became “Di Renjie after Biography.”
