So even though Fox hasn’t had great luck with Marvel’s First Family, they’re not planning on partnering with Marvel anytime soon.
Scott Derrickson is definitely not the first person to hope that the Fantastic Four will one day be added to the MCU, especially following the 2015 reboot bombing both critically and commercially.
Still, Marvel and Sony eventually worked out a deal to share Spider-Man, so never say never.
Unfortunately for those people, that won’t be happening anytime soon.
