Note: This is a Fan-Cast for a multi movie Spider-Man story arc taking place within the Marvel Cinematic Universe. I left out either of the two main love interests in order to focus more on other character dynamics. I also did not cast Norman/Harry Osborn because we have already seen that storyline done twice. The story arc would focus on the relationship between Peter and Eddie as they grow to become enemies and then to team up to defeat Carnage in the climax of the arc.
Plot: Childhood friends Peter Parker and Eddie Brock Jr. reunite for the first time since their parents died in a plane crash. Together they discover work their fathers did on Project Venom, an attempt to recreate the Super Soldier Serum. Peter, an amateur photographer, also has a secret of his own he is hiding from Eddie.
