Perhaps I read too much into this, but I thought the friendship between Zuckerberg and Saverin in The Social Network ran very much parallel to the friendship of Jedediah Leland and Charles Foster Kane in Citizen Kane. The disillusionment that Leland faces in having to expose his friend, Kane, as a fraud insofar as a man abandoning his core principles in running a newspaper to become a power hungry politician is in line with what Saverin faces in watching Zuckerberg be taken in by interloper Sean Parker and Parker's influential ideas on how to expand Facebook.
Both films feature scenes where the best friends of the lead characters confront their friendship/conflict while reflecting nostalgically on their declining importance; Leland's saved declaration of principles from the hand of a younger Charles Foster Kane and Saverin during a moment of reflection with Zuckerberg discussing an algorithm written on a dorm room window pane.
Both films are classic tales of young entrepreneurs becoming wealthy, powerful and influential...albeit without any friends.
