Overstreet, a Tennessee native whose credits include an appearance on the hit Nickelodeon tween series "iCarly," will appear on Fox's musical comedy as Sam, a high school athlete who becomes a protégée of Finn's (Cory Monteith) and ultimately turns into his competition. His appearances will begin with the "Glee" season premiere, Sept. 21 at 8 PM ET.
As previously reported, Overstreet's fellow "Glee" second season guest stars will include stage and screen star John Stamos as a dentist who will be dating Emma (Jayma Mays); Oscar winner Javier Bardem as a heavy metal rocker; and Filipino singing star Charice as an exchange student who becomes a rival to Rachel (Lea Michele). Tony Award winners Idina Menzel and Kristin Chenoweth are set to reprise their first-season guest roles as, respectively, rival glee-club music director Shelby Corcoran and down-on-her-luck former glee club star April Rhodes.
According to FOX, "'Glee' is an uplifting series with biting humor that features a soundtrack of hit music from past to present. The show follows an optimistic high school teacher, Will Schuester (Matthew Morrison), as he tries to refuel his own passion while reinventing the high school's glee club and challenging a group of outcasts to realize their star potential. It's not an easy task when the pitch-imperfect club includes Mercedes (Amber Riley), a forceful diva-in-training; Arty (Kevin McHale), a geeky guitarist; Kurt (Chris Colfer), a dramatic soprano; Tina (Jenna Ushkowitz), a punk rocker; and self-proclaimed 'star' Rachel (Lea Michele), a perfectionist firecracker.
"McKinley's cruel high school caste system prevents the glee club from flourishing, so Will recruits Finn (Cory Monteith), the quarterback with movie star looks, to join the group even though he wants to protect his reputation with his holier-than-thou girlfriend, Quinn (Dianna Agron), and his arrogant teammate, Puck (Mark Salling). With harsh criticism from everyone, including Will's tough-as-nails wife Terri (Jessalyn Gilsig) and McKinley's egotistical cheerleading coach Sue Sylvester (Jane Lynch), he is determined to prove them all wrong and lead the glee club to the greatest competition of them all: Nationals."
The second season of "Glee" premieres Sept. 21 at 8 PM ET on Fox.
