It was bound to happen eventually, and I had a feeling Fox was going to the company that finally made it happen.
Ever since Marvel Studios started making their own movies, fans have been wondering about the possibility of the characters that are currently owned by other studios making crossover appearances into the Marvel Universe that's been built, film by film, over the last few years.
Today, it looks like that's starting to happen, and it's a fairly exciting development in terms of what opportunities it sets up for this second wave of Marvel movies and also for one of the characters that is staying at Fox. David Slade recently left the "Daredevil" reboot that Fox has been developing, and now it looks like Joe Carnahan may step in with a take that is being described as a "Frank Miller-esque hardcore '70s thriller," which sounds like the exact right approach to the character. Carnahan hasn't commented officially, but he just Tweeted a very cryptic "DD - MM - 73," so feel free to interpret that as you see fit.
It sounds like it's still premature to say that's a done deal, but time is something that Fox does not have on their side right now. They have to make a "Daredevil" movie sooner rather than later, or the rights revert to Marvel. That's something Fox would like to avoid, and since they have a bargaining chip, it looks like they're going to play a lightning round of "Let's Make A Deal" where the real winner will be the audiences.
