Unscripted series takes over for 'Donnellys' April 23

Having had less-than-stellar results with dramas in the 10 p.m. Monday spot this season, NBC will take a flyer on unscripted comedy to close out the year.

The network has set a premiere date for "The Real Wedding Crashers," a hidden-camera show based on the hit 2005 movie. The show, produced by "Punk'd" maestros Ashton Kutcher and Jason Goldberg, will debut at 10 p.m. ET Monday, April 23, following the return of "Heroes." It takes the spot of "The Black Donnellys"; there's no word on when that show's remaining episodes will air.

A group of five improv performers will take to the churches and reception halls or our fair nation, posing as guests or cater-waiters or other attendees to disrupt the proceedings, presumably to make sure that the happy couple never forgets their wedding day.

One catch: The bride and groom know what's coming. They're in on the joke and will help the "crashers" reveal the hoax at the end of each episode. Some of the hijinks will even be designed to bring families closer together, presumably in more than just horror at the behavior of the crashers.

The cast features Ben Gleib, Steve Byrne ("Comedy Central Presents"), Desi Lydic ("Invasion Iowa"), Gareth Reynolds and Catherine Reitman ("My Super Ex-Girlfriend"). Kutcher and Goldberg are executive producing with Karey Burke, Rich Meehan, Jon Kroll and Jim Rosenthal.
