Fox went right down to the wire with the last movie though with less than a year to go. Maybe even only a couple of months or so. We speculated that they wouldn't move forward with it as it was getting so late and delayed so many times, but they still did. Could they be that idiotic again?
I'm not sure if it was as likely they would quit as most of us hoped.
In March 2014 (nearly a year and a half before release) we had our best hope when it was reported they were looking for new directors. They probably were, but by that point, they were too far along and needed a director who could step right in. They didn't have enough time to start all over. And when they couldn't find one, they had to continue with Trank.
By that point, it wasn't just the Marvel agreement that was putting a gun to their heads. Management was also (foolishly) counting on FF to be their 2015 tent-pole. In today's film world, studios need films like DOFP to make the year for them and be the difference between black and red on the big ledger. Without a big enough hit to make the year . . . well we saw what happened to Fox and their stock in 2015.
By March of 2014, it was too late to pull a new tent-pole out of their butt, so they needed to push through with Fant4stic and do whatever they could. Without a competent director to take over, they fumbled along with Trank as the official director and others, almost certainly, taking over his directorial duties.
Fox should have learned some things from this:
1. Josh Trank and Simon Kinberg are idiots.
2. Fox is incapable of making FF movies.
3. If they do make the foolish decision to attempt another FF film, they should give themselves more time and not schedule it so they are trying to release it the year their rights expire.
I'm saying five years because I think that if we haven't heard anything five years from now, we're safe.
But more realistically, Fox should be moving more quickly than that. If they don't want to put themselves in a similar position in the future, they should shoot for 2022 instead of 2023.
And if they want to make a serious effort at an FF film in 2022, they should be working it into their schedule and lining up a good director and script well prior to that.
So I think if Fox really, seriously wants to take another shot at this, they should begin putting it together by around 2018 - two years from now. I can't imagine management would seriously let them loose on a new effort in two years, so the chances are close to zero they'll even attempt anything again.
But from our point of view. If we ask ourselves "What's the absolute longest we could go without hearing anything but Fox could still slap together a film?", I think that number is five years. If we don't get any announcements over the next 5 Comic-Cons, I think we're safe.
