A Geeky Viewpoint

I was a little shocked to hear that another Fantastic Four script is being looked at and or considered by 20th Century Fox.

Okay shocked is not the correct term as per the contact 20th Century Fox has to have another film in production in the near future (dates vary by source from 2017 to 2019) or the IP is turned over to Marvel Enterprises.

But why now?
The last film was a total flop, IF 20th Century Fox thinks they can make more money selling the IP back to Marvel getting something moving will actually force Marvel to move forward rather than sit back and wait.   It is a typical business position to attempt to force you partner to move first.  

What's the IP Worth?
That is an interesting question, while I don't have an exact amount I'd guess somewhere between $250 Million and $500 Million right now to Marvel.    No one else would pay that amount but Marvel might under the right circumstances.

Why is it worth so much to Marvel Studios?
One word - Villains. 
Marvel Studios now controls the IP for many Super-Heroes, the story on Villians is another story.   Most of the space based Villains belong to the Fantastic Four IP, including the likes to Galactus and Doctor Doom.   Many of the street level villains belong to the Spider-Man IP and X-Men has a long list of villains in their IP.

When could we see public activity?
I would be shocked if third parties haven't acted as go between at a minimum in this situation so far, but direct talks might not be out of the question either.  

So what is this new script you are talking about?
I don't know when this script was originally written or how official it is and there is lots of issue with its validity in the first place.   It could simply be a interweb rumor/hoax (not that it would be a first) nor the even the first I liked.   None the less.  

The potentially new script is a soft reboot of the 2005/2007 films as opposed to a hard reboot like the 2015 film.    Being a soft reboot it is not an origin story, the Fantastic Four have their powers to begin with.   It also means that events in the first two film kind of happened.   They may not focus on them, but there is no denying what did happen.   In the same family as the soft reboot with Incredible Hulk (2008) to Hulk (2003).

My feelings?
I this point I have to think this is more of a ploy to increase the value of the IP and force Marvel's hand than to actually make another movie.   I thought that before and we got Fantastic Four 2015, so I guess anything is possible.
