NBC has set an hourlong special with comedian and ventriloquist Jeff Dunham.

“Jeff Dunham: Unhinged in Hollywood,” which will be taped August 19 at the Dolby Theater to air on Sept. 17, will feature a combination of comedy acts and live musical performances.

Among the stars scheduled to appear are country music’s Brad Paisley, comedian Chris Parnell and MMA fighting champ Chuck Liddell — along with Dunham’s cast of characters, including grumpy old man Walter.

“NBC has been very good to me over the years, and it’s a true honor to have a special on the network,” said Dunham. “Walter said he’s looking forward to performing again in the showbiz/divorce capital of the world.”

The Sept. 17 special will also include behind-the-scenes footage of the August show.

Dunham is repped by LEG, UTA, Morris, Yorn, Barnes and Levine.
