The cast of the much-hyped show "Glee" walked the red carpet on the eve of the show’s television premiere. Jessalyn Gilsig — who plays the nagging wife to the high school Glee Club teacher-- tells ET, "We're just making the show that feels true to us and that's what people responded to in the pilot, so I think we feel confident going forward." "Glee" cast member Matthew Morrison -- who plays Glee Club teacher Will Schuester -- is excited to share his passion for musical theater with a television audience. He says, "I love coming to work and getting to sing." The show has challenged him to "flex some different muscles" vocally and do a rap number.
