搵到篇06/02嘅都係咁講, 以我理解1000頁係3集嘅notes嚟
交俾Robert嗰600係一早俾咗, 亦應該係包含埋第2集嘅故事
Rodriguez admitted that Nova was tough to cast, as his presence is "really for the setup of a sequel". Wanting to make sure the small, non-speaking role was filled with someone they would want to work with on the theoretical Alita: Battle Angel 2, they eventually cast Edward Norton in the role. Another character, Clive Lee, was in the original script but was cut. "I figured we should save him for a sequel," said the director.
There is definitely no shortage of plans for a follow-up. Rodriguez said that Cameron told him he wouldn't send "all the 1,000 pages of notes". "I’ll send you like 600," Rodriguez quoted, thinking that Cameron was joking before 600 pages of notes on the Alita script arrived in the post.
