"We have all sorts of vocal styles, but also kids that represent aspects of high school and that world.
"What's wonderful about Glee is that it is about the misfit, it is about the underdog, finding your differences and celebrating them."
Urlich has an eye for picking the ultimate show choir performer.
There was no part for Chris Colfer, who now plays Kurt, when he turned up to audition a few years ago.
"He was so special ... on the spot he created the character of Kurt. Now it's inconceivable that the character did not exist, but he didn't."
Urlich hopes The Glee Project will introduce a new intake of characters that will keep the show fresh and the actors realistically high-school-aged.
Unlike the hit British teen drama Skins, which renews its entire cast every few seasons, Urlich does not think Glee fans could cope with him replacing the whole cast in one hit.
Stepping off the set of Glee and on to The Glee Project helped Urlich understand how much Murphy's TV show had not only resonated with young people but taught them important lessons about bullying, homosexuality, pregnancy, alcohol abuse and, above all, acceptance.
"So much of Glee's success is that everyone has been in high school, and high school really hasn't changed. It's still that time when everyone wants to be liked, people are dealing with their insecurities, and jealousy, and everyone knows these characters and sees a part of themselves or someone they know in these characters.
The Glee Project is like a glimpse into real life high school, it's like real life Glee club," he says.
