Big changes are taking place behind the scenes of Fox hit “Glee,” which is hiring a writing staff for the first time as it readies the show’s third season. In the show’s first two seasons, all episodes have been written by co-creators and executive producers Ryan Murphy, Brad Falchuk and Ian Brennan.

A key to the new arrangement is the hiring of "Buffy" and "Angel" veteran Marti Noxon as a consulting producer, reports Deadline.com. Also joining the show will be Allison Adler of "Chuck" and "No Ordinary Family," who signs on as a co-executive producer, the story says.

Roberto Aguirre-Sacasa, who worked on the rewrite of the Broadway show "Spider-Man: Turn Off the Dark," is joining as co-producer, and staff writers Matt Hodgson and Ross Maxwell are also on board.

The lack of a supporting writing staff was apparent during the second season of the show, when "episodes were uneven and often felt like standalone movies built around songs, with the overarching storylines sometimes fractured or meandering," the story says.
