The cities (and colleges campuses) we see in the movies are not always what they claim to be -- and that doesn't go over well with students at Johns Hopkins University. The Social Network is currently being filmed at Hopkins, which is in effect playing the part of Harvard, which doesn't permit commercial films to be shot on its campus. The fee the university is receiving isn't enough to justify pretending to be Harvard, students told The Baltimore Sun.  They fear Hopkins looks like a safety school. "The general consensus is, a lot of kids are not pleased," one student told the Sun. "It's obvious they [the filmmakers] could get Hopkins and not get Harvard."
