Ryan Murphy to Replace 'Glee' Cast After Season 3
This isn't a rash decision -- Ryan had thought about this way back in December 2010. "The thing that I wanted to do and the cast wanted to do, we didn't want to have a show where they were in high school for 8 years," he added. "We really wanted it to be true to that experience. We thought it would be really cool if we were true to the timeline."
Matthew Morrison and Jane Lynch will stay on as Will Schuester and Sue Sylvester, but unknown actors will make their way into William McKinley just as Darren Criss and Chord Overstreet did last season.
"I think the fun thing about the show is it's a celebration of youth and talent," Ryan continued. "And I think that just like with the original cast, I think finding those young unknown people and giving them an opportunity to break into the business and become stars is a really fun and exciting thing, and is the spirit of the series."
