Because of the Sony Pictures hack in 2014, it was revealed that the lineup for The Sinister Six would have included: Doctor Octopus (as the leader) Sandman Vulture Venom Carnage As well as Black Cat Scorpion
The symbols of each Sinister Six member were featured in the credits of The Amazing Spider-Man 2 (2014).
Even though Marvel is now making the next Spider-Man trilogy, there is still plans to put out The Sinister Six but delayed from the original November 11th 2016 date.
As of February 2015 the Film is still moving forward with production after Spider-Man's acquisition deal with Marvel and Sony for creative rights of the character, but canceling the Amazing Spider-Man 3
This film was originally a spin-off from The Amazing Spider-Man series and would feature Dane DeHaan, Paul Giamatti and Chris Cooper returning to the roles they played previously. Jamie Foxx, Rhys Ifans and Andrew Garfield were also rumored to cameo. This plan fell through after Sony's Email Hack scandal in 2014 which later influenced the decision to collaborate with Marvel on future Spider-Man projects. In effect, this film was not cancelled, instead pushed back to after the new Spider-Man films were established.
