Last week I saw some rumors about Sony Pictures' Sinister Six film being cancelled. I never posted the rumors because it sounded like pure speculation, and it was. The studio has announced that they will release the villainous Spider-Man spin-off film on November 11th, 2016. The Amazing Spider-Man 3 will follow a couple years later and is going to be released in 2018. It was supposed to be June 10th, 2016, but Sony moved their Uncharted film adaptation into that spot.
Drew Goddard (Cabin in the Woods) is attached to write the film, which will expand the Spider-Man cinematic universe. He may end up directing it as well.
The supervillains first appeared in 1964, and they included Doctor Octopus, Electro, Kraven the Hunter, Mysterio, Sandman, and the Vulture. I assume Spider-Man is also going to be a main character in this film. I don't see how they could make a movie without him. Both projects will be produced by Avi Arad and Matt Tolmach.
