Nicholas Stoller is a natural romantic, but his films aren't your run of the mill romantic comedies. His directorial debut, Forgetting Sarah Marshall, which he co-wrote with frequent collaborator Jason Segal, was a unique combination of romantic and screwball comedy, with a full-scale musical finale. He has continued to push the romantic comedy genre into new realms with films like Get Him to the Greek and his latest, The Five-Year Engagement, starring Jason Segal and Emily Blunt. Elvis talks to Stoller about his surprising start in advertising, the films that influence him most, and what he's learned about relationships.
