Neil Patrick Harris: "Glee" Club Survivor?

More information is trickling out about Neil Patrick Harris' upcoming guest turn on FOX's musical-comedy Glee this May.

Entertainment Weekly's Michael Ausiello is reporting that Harris will play Bryan Adam, a former glee glee club nemesis of Matthew Morrison's Will, who is now as a William McKinley High board member in the episode, to be directed by Buffy creator Joss Whedon.

Citing an unnamed Glee insider, Ausiello goes on to report that the high school feud between Harris' Bryan Adam and Morrison's Will will be depicted via flashbacks which will show the two as rivals for solos and girls as teenagers... and that animosity has carried over into adulthood, where Bryan is now looking to cut the arts program.

"Show choir ruined his life, made him feel he could be a star, but all he could do is book Carnival cruises,” the unnamed Glee insider told Ausiello. "Now he wants vengeance."

I'm happy to add some further details to Ausiello's report as it now seems as though Harris' Bryan Adams is in a glee club survivors support group that will also be populated by Molly Shannon's character.

The word comes from the most recent casting breakdown for Glee, which is looking to cast a new character, "Russell" as one-day guest star with the potential to recur on the 20th Century Fox Television-produced series:

"[RUSSELL] Late 30s-40s. He is a member of a "Glee Club Survivors" support group which includes other members Neil Patrick Harris and Molly Shannon. PLEASE SUBMIT "NAME" as well as "NON-NAME" actors...ONE-DAY GUEST STAR (POSSIBLY RECURRING)"

Which makes me wonder: just who else is part of this support group cabal? And are they all plotting the demise of McKinney's Glee Club?

Glee is set to return April 13th at 9 pm ET/PT on FOX.
