A while back it first reported by Murphy’s Multiverse that Disney had listed a new LLC called Solve Everything Productions, that we were able to back-up. The claim made was that it was likely hinting to the studio moving forward with their Fantastic Four reboot before tackling X-Men.
A small update from Charles Murphy further confirms that the Disney-owned LLC is indeed at Marvel Studios. This would mean that they’re going into production on the project which is most likely going to be Fantastic Four given the LLC’s name is connected to the Marvel Comics property.

However, it’s worth noting that Marvel/Disney and trades have yet to announce any screenwriters or directors have joined the project, let alone they are moving forward with a Fantastic Four film or series. All signs are pointing towards a Fantastic Four project will be announced in the near future and could be primarily filming in the United States.
The Fantastic Four has had four live-action films starting with the Roger Corman-produced film from 1994 that was ultimately never released and then 20th Century Fox released two installments from director Tim Story then attempted a reboot from Josh Trank in 2015.
The film rights shifted back to Marvel once Disney finalized their acquisition of 21st Century Fox (included 20th Century Fox). Marvel now has access to Fantastic Four, Doctor Doom, The Brood, The Shi’ar Empire, Alpha Flight, X-Force, New Mutants, X-Men, Deadpool, Wolverine, Silver Surfer, Galactus, Super-Skrulls, and many many more characters to use for their MCU projects.
A one time, writer/director Adam McKay (Ant-Man, Vice, The Big Short) was interested in pitching a Silver Surfer film to Marvel’s chief creative officer Kevin Feige.
