With all the superheros in NY, (Spiderman, Fantastic 4, Xmen, Daredevil, etc...) why don't any ever crossover?
They have ran into each other many times in the comics. Currently, Peter Parker(Spiderman)is working for Tony Stark(Iron-Man). This is both as Parker and Spidey. Spidey was briefly a part of Fantastic Four and the Avengers. I remember a specific time that DR Strange was in trouble and sent a psychic message to Spiderman for help because he was the closest superhero. In the comics, any superhero can run into another and often does. As for the movies, they are seperate to make more money and have their own story lines. In Fantastic Four the movie, there are no other superheroes making them unique. However, DC has been talking about a Batman & Superman movie for a while now. It's kinda like Alien Vs Predator...they both had their own series, but came together in time.
