10 Cancelled Movie Sequels (That Could Still Happen)

Cancellation

Similar to Doctor Doom, Sinister Six would've been a sequel in the sense that it was planned as an offshoot of Sony's Amazing Spider-Man franchise, which featured Andrew Garfield as the titular web-slinger.

The movie - a team-up featuring a roster of notable Spidey villains - was first announced in December 2013, but when April 2014 rolled around and The Amazing Spider-Man 2 underperformed, the future of the series was left in serious doubt.

Months later, Sony signed a deal with Marvel and Disney to bring Spider-Man into the Marvel Cinematic Universe, cancelling the proposed Amazing Spider-Man 3. Meanwhile, any and all spin-off movies that Sony had in the works at the time - including Sinister Six - were believed to have been cancelled as well.

Why It's Not Dead

It's not often that you hear of a movie dying in one cinematic universe and being resurrected in another, but this might just be the case for Sinister Six.

Even after Spider-Man entered the MCU, the project kept cropping up in the news every couple of months, and in December 2018 - shortly after Sony achieved massive success with Venom - former Sony Pictures chief Amy Pascal said that she was "waiting" for previously-announced writer-director Drew Goddard to be "ready" to make Sinister Six.

Then, in October 2019, Pascal once again hinted that the project was alive, saying that all the Spider-Man villains that have been used in recent movies may eventually form the basis of the Sinister Six team:

"All of these villains that we now have in our universe happen to be characters that are in the Sinister Six. There may be something that happens with that."

Interestingly, that quote is pulled from Spider-Man: Far From Home's special features, meaning that Sinister Six could end up using villains from the MCU - like Vulture and Mysterio - along with villains from the Sony-verse, like Morbius and Venom.
