We've so far seen very little from Venom but during an appearance - via video package - at the Comic-Con Experience 2017 in Sao Paulo, Brazil, director Ruben Fleischer revealed which comic book storylines have influenced the upcoming movie which stars Tom Hardy as Eddie Brock. While we've already heard that the Lethal Protector storyline will come into play, it turns out there's another.
That is Planet of the Symbiotes, a lesser known arc which was written by David Michelinie. In that, Venom teams up with Spider-Man and the Scarlet Spider to investigate a series of symbiote related murders he's been accused of committing. It turns out that the five symbiotes who first appeared in the Lethal Protector story arc are to blame and are building a teleporter to bring the aliens to Earth.
That could take Venom down a sci-fi heavy route and seeing as Carnage also factored into the story, chances are Cletus Kasady could make some sort of appearance. Of course, very little might have actually been taken from both of these comics when all is said and done so we'll have to wait and see. With the movie coming our way next year, though, chances are we'll start hearing more details soon.
