In a recent interview with MTV News, Marvel Studios President Kevin Feige commented on the question about any Spider-Man spinoffs in the works like the Sinister Six film, Spider-Gwen or a Venom film. Here’s what Feige had to say.
“Well, there could be [spin-offs]. But the truth is, our job right now is that single Spider-Man movie based in the MCU. And that’s where all our focus is.”
So it looks like they are aware about the other character they can tackle down but the main priority is Spider-Man and making him fit perfectly into the Marvel Cinematic Universe.
