·在最初的剧本创作计划里,编剧帕特里克·奥尼尔将本片命名为“All New Enemies”(《所有的新敌人》),后来又改为“TroubleMan”(《麻烦的男人》),后来在拍摄的时候又改为“Wichita”(《维琦塔》),在《维琦塔》几乎成为最终片名的时候,本片终于定名为“Knight and Day”(《骑士与白天》),也就是如今的官方译名《危情谍战》。本片的的故事经过了Scott Frank、DanaFox、 Laeta Kalogridis、 Ted Griffin、Nicholas Griffin、 TimothyDowling、 Simon Kinberg等人的修改和增订,最后由导演詹姆斯·曼高德确定了最终的故事剧本。
Milner: On the count of 3. Ready? 1...
[June runs around madly while she is shot at wildly]
June Havens: Sorry! I panicked!
Milner: What number would you like?
June Havens: Three. Yeah, let's just stick with three. It's good.
Milner: Okay...
米尔纳:“我数到3就行动。准备好了吗?1……”
(茱恩冲了出去,然后疯狂的跑来跑去躲避子弹)
茱恩:“对不起,我实在太害怕了!”
米尔纳:“你喜欢什么数字?”
茱恩:“3。啊,让我们直接数到3吧,那就太爽了。”
米尔纳:“好吧……”
Milner: Some people are gonna come looking for you now.
June Havens: Why?
Milner: They'll tell you I'm mentally unstable and violent and dangerous and it will all sound very convincing.
June Havens: I'm already convinced.
米尔纳:“有些人会过来找你。”
茱恩:“为什么?”
米尔纳:“他们会告诉你,我精神不太稳定,而且有暴力倾向,是个危险人物,他说这些话的时候的语气会非常有说服力。”
茱恩:“我已经被说服了。”
June Havens: The pilots are dead!
Milner: Yeah, they've been shot.
June Havens: By who?
Milner: By me. No, actually, I shot the first pilot then he accidentally shot the second pilot. It's just one of those things.
茱恩:“飞行员都死了!”
米尔纳:“哦也,他们都被枪干掉了。”
茱恩:“被谁干掉的?”
米尔纳:“被我。不,实际上,我只是杀了第一个人,然后他很意外的把第二个人干掉了。这只是件小事而已。”
