The connection between Green and Judd Apatow’s gang is a lot more confusing to writers and critics then it is to Green himself. After hanging out with Apatow and Seth Rogen on the set of Knocked Up, he was able to see how similarly they approach filmmaking. Each consistently works with the same people, including cast and crew, and both seem interested in making coming-of-age tales, with a great deal of focus on their characters. Green’s characters are usually based on people he sees while riding the bus rather than clichés or stereotypes.
