Colfer played Kurt Hummel on the show since the series began in May 2009. The 24-year-old actor has received several awards for his role on the musical comedy, including Best Supporting Actor in a Series, Miniseries or Television Film at the 2011 Golden Globe Awards and two People's Choice Awards for Favorite Comedic TV Actor in 2013 and 2014.
Colfer, Lea Michele, Matthew Morrison, Jenna Ushkowitz, Kevin McHale and Naya Rivera are a few of the original cast members that were set to star in the show's last season, which is expected to air in 2015 on Fox.
