I woke up like this, wondering what's going on with Colin Firth and Nicole Kidman and/or their agents?
People aren't talking about this yet because the movies haven't arrived and also, undoubtedly because both stars are so prolific that it's hard to keep track of their upcoming deals. But three of their next handful of releases are together. They're husband and wife in The Railway Man (opening in April) which is largely Colin's film. Then they're nemeses in Paddington (opening in December) in which Colin is the voice of the title character and Nicole the villain. And at some point (no release date yet) they're back to being husband and wife again in the thriller Before I Go To Sleep in which Nicole plays a woman being treated for anterograde amnesia who doesn't realize she's married or has a son.
Will Colin & Nicole do a fourth? I feel they must. In their two films in which both actually appear, Nicole is brunette or blonde but you haven't really co-starred with Nicole Kidman unless she's a redhead.
That's the rule.

Though frequent pairings have a rich history in Hollywood, it went out of fashion sometime in the modern era. (Maybe franchise culture killed the desire for it, since there is so much repetition in other ways?) Frequently co-starring with the same person just isn't that common anymore outside of auteurist filmographies that use the same actors a lot in different permutations (Cooper & Lawrence & Russell lately). It's not even common when we want it to be (I'm still waiting for Brad & Angie to follow up Mr & Mrs Smith you know? And despite several indications over 25 freaking years that Pfeiffer & Bridges wanted to pair up again it never happened). It's not even common to continue even when all of the pairings are big hits (Turner + Douglas and then Hanks + Ryan quit after only three).
Who do you wish would be reunited onscreen? Will Colin & Nicole do a fourth? Stay tuned.
