Sony has just announced plans to release a Venom movie in October 2018. Now it's no secret that Sony has been keen as mustard to incorporate Venom into their Spider Man-verse, with the black alien goo practically being forced into Spider Man 3, a planned Venom movie in The Amazing Spider Man continuity, and an appearance in the proposed Sinister Six movie. So it really shouldn't be too surprising to hear that a Venom is still on the cards, but what is surprising is that the Venom is rumored to be a part of a separate continuity to that of the Spider Man: Homecoming one.
I find it hard to imagine how a Venom origin movie could realistically work without the inclusion of Spider Man himself. The two are so inextricably linked to each other that any attempt to tell Venom's story without exploring Spider Man's backstory would just seem awkward. Venom arguably only really shines as a character because of his development with Spider Man, that of course stems from the strained relationship between Eddie and Peter. Even if they do connect Venom to the main Spider Man universe, I really feel like that would be far too early to introduce the maniacal symbiote. Venom is a problem for adult Spider Man, not boy Spider Man. It makes me wonder if Sony could be planning to explore some of the many alternate Spider Man universes that exist. That way they could have their Marvel boy Spider Man while also exploring the more mature adult Spider Man stories.
There are other potential candidates they could use instead of Eddie Brock for Venom, but I feel like Eddie is simply too synonymous with Venom. Just like Spider Man is Peter Parker, Batman is Bruce Wayne, and Iron Man is Tony Stark. I'd like to see a trilogy of movies that properly explore Peter Parker and Eddie Brock's relationship, then Eddie Brock's descent into madness, and then something along the lines of a Maximum Carnage adaption. Problem being is that it would necessitate an R rating to properly tell those stories, and I highly doubt that Sony are willing to go that route, especially now since they're involved with Disney. Details are scarce at the moment, but it'll surely be interesting to see how this all pans out. Even still, I'll remain skeptical about it.
