Before the Hollywood Strikes issued an aggregate halt on the entire production of the entertainment industry, there were still several projects being developed by studio's covertly; before they were ready to be announced, and move forward to the beginning stages of production.
Rumor has it, a solo Ghost-Rider project was secretly being developed by Marvel before the strikes begun - the rumor comes from @MyTimeToShineHello:
While this rumor has not been confirmed nor denied, the post claims that once the Hollywood Strikes fully come to a close, Marvel will move forward in developing the project.
If this does turn out to be true, the solo-project could potentially be a Special Presentation feature for the character, much like how they did Werewolf By Night; but of course nothing is known yet about the project, much less its screening.
If Marvel does move forward in making the Ghost-Rider solo-project, it would be another step in the right direction to incramentally introducing all the members of the Midnight Sons ensemble within the Marvel Cinematic Universe.
So far those who have been introduced within the MCU are Doctor Strange and Moon Knight - soon-to-be Blade, and if they move forward with the project, Ghost-Rider.
There have been nods (Read Here) to Ghost-Rider already in the MCU, exclusively in the She-Hulk Disney+ series, which makes the chances of Ghost-Rider wheeling his way into the MCU sometime soon all the more likely.
Would you like to see a Ghost-Rider solo-project?
